Hello! I have a few suggestions for the manuscript, likely noted by reviewers assuming this was submitted to a journal. First, include the metric used on each dataset for Tables 2 & 3. And second, try using splits that are not randomly selected for evaluation -- KMeans clustering can be done on embeddings or clustering by sequence with MMSeqs2 is another option. This will give a better idea of model generalization to unseen sequences.

Great work - really glad to see attention on natural plant extracts against SC2 replication such as the study of artemisia annua. I hope the comments below will be seen in that light - 80% supportive, 20% constructive critical review to support it becoming even better:
My lab would be very happy if the relevant active phytochemicals in a. annua or a. afria for potency against SARS-CoV-2 replication were identified, whatever they are. That said, I feel that members of the flavonoids class haven't been ruled out yet: While valuable to recognize and assay flavonoids as a monolithic class, there are still very different flavonoid molecules among them that cluster to make up the different classes of flavonoids (flavans, flavanones, etc.). Then there are the glycosidic states of each flavonoid - i.e. does it have one or two sugars attached via a glycosidic linkage? Our in silico modeling shows that these states can have profound effect on limiting SARS-CoV-2 replication. (Note this critique doesn't apply to the statements made with regards to artemisinin, being one single unambiguous molecule)
It would be very easy for a an operative flavonoid molecule to show up more in one cultivar of a. annua than another, such that even while no association could be shown to total flavonoids, rather that individual flavonoid species vary across the cultivars in such a way that studying a correlation of "flavonoids" collectively against viral inhibition would mask. Our posted work provides justification for just such flavonoid candidates specific to a.annua, and I would be happy to direct these diligent authors toward it with accompanying context.

I very much enjoyed reading this proposal. I agree with the need for dramatic improvements in the way journals handle the post-publication modification to articles.
Some general reactions/thoughts:
Newspapers vs. Scientific Journals. I find it difficult to pinpoint the key difference between newspaper articles and scientific journals, making me wonder why the simple approach many newspapers have taken to amending articles cannot work for scientific journals, or at least be the basis for the approach journals take? I think the key would be that journals would do a better job at allowing an audit trail. The audit train would make transparent the nature and timing of the changes, make obvious to the reader which version they are viewing at any given time, and add on electronic features such as the ability to compare any two versions a reader wants to compare, showing tracked-changes version between those two versions.
What to call it. I agree with the authors that terms like “correction” and, in particular, “retraction” are problematic in that they are perceived to necessarily convey more than the straightforward act of a post-publication change to an article. I agree that the term “amendment” is neutral, but I have trouble with it. My trouble is that one dictionary definition of “amendment” is a “minor change in a document”, whereas you are conceiving this as an overarching term including changes that may be large. My second difficulty is that it suggests adding something to the document, as in an appendix, not necessarily changing the document itself (albeit in ways that are transparent). Did you consider “alteration”, “version”, or “revision”? Journals generally use “revision” to characterize different version of a manuscript in the pre-publication phase. Is there any good reason not to use it post-publication? There can be minor revisions and major revisions, insubstantial, substantial, and complete revisions… so the term has the flexibility I think you’re looking for.
In terms of contextualizing the topic, I think something needs to be said describing the old world of print only vs. the new world of print and online. With print, there was a clear ORIGINAL publication. No matter how flawed, once printed on paper, one couldn’t amend the true original in the library stacks, but only issue further statements ABOUT the article (corrections, editorials, notices of concern, retraction NOTICES). With online comes the possibility of editing the original – or at least what appears to be the original (i.e. the version people will see when they attempt to access the publication from the publisher’s website). This added complexity can help reduce the propagation of errors (small or large) that may have existed in a publication.
This point is not just stylistic. I think it gets at the heart of whether or not the first published version should means anything special. We are used to thinking it does. But the authors discuss protocols (under “A proposal for the future”) which raises the question of publishing documents that have mostly not undergone editorial processes. So when does the first version start, and what does it represent? Is it the first version that the authors ever drafted or is it the version accepted for publication i.e. the culmination of many revisions pre-publication? Is the idea that once a document is made public (i.e. published), then thereafter, all changes, big or small, will be tracked?
What does one do in the event that editors are convinced of an error that needs correcting but the author(s) adamantly refuse? I know the correction notice can carry words to the effect that the editors are fixing what they deem to be an error but if the authors disagree, will the actual article be amended yet still carry the authors names in the byline? That seems highly problematic as it attributes words to them that they do not stand by. The only way I can see to deal with this is to issue, depending on severity of error, a retraction against authors will or, alternatively, a linked ‘expression of concern’ but not change the actual text of the article. Any kind of modification of the original where even one author dissents seems problematic. It would get even more complex if some authors agree with the amendment yet others do not. Do we get version forking with editors to decide which version is served up as “current”?
I would avoid introducing protocols into the single-stream publication proposal. Protocols are one of many essential documents involved in research. A research paper another one of those essential documents – but again there are many important documents with research. Protocols often go through their own many revisions and, practically speaking, are different files on one’s computer that may exist simultaneously to a manuscript that is in preparation. It seems to me your proposal should track the versioning of a single document – e.g. the journal-destined research report – possibly pre-, but definitely post-publication in a journal.
Stylistically, the concept the authors put forward (of conceptualizing the amendment process as containing two distinct elements of (1) editing articles and (2) publishing a notice about the edit) is important and I think can be made clearer earlier on, perhaps giving it its own heading “The amendment model: publish a notice and edit the article itself”.
Also stylistically, I would put more emphasis on the point that in the case of a correction, irrespective of the size of the correction, articles available online will be edited so that by default, the version served up to a reader when they visit the article on the web will be the CURRENT version (reflecting all edits/corrections to date), not the version that appeared when the article was first published (with a notice that a correction exists). I think this is a big break from current practices at many journals.
The authors note that every publisher has their own strategy for content delivery, and do not make specific recommendations for or against how to display amendments. But it seems to me that display strategies are part of what has got many people feeling uncomfortable about corrections. Many authors probably would prefer to avoid a big bold all caps notice that THERE HAS BEEN A CORRECTION TO THIS ARTICLE at the top of their published article? I think therefore that a specific recommendation for how the reader should be alerted about the existence of amendments should be made. The authors suggest a difference in display between minor vs. other amendments, but I wonder if there should just be one approach in line with the notion of de-stigmatizing amendments.
As far as locations for noting the existence of post-publication amendments, newspapers are doing it below the article, often set apart with italicized text. Where will this flagging occur in scholarly publishing? What about proposing certain article meta-data become standard. Just the way Acknowledgements and COI declarations are now fairly standard elements of articles, could a “Current version: X (version history)” line become standard, with a link to a separate document that contains the explanation of the corrections? Or perhaps all articles should contain a "Version history (up to [YYYYMMDD]): On YYYYMMDD, we fixed a typo. On YYYYMMDD, we removed an author for reasons described here (DOI-to-editorial-note-about-research-misconduct)..."

Dear Carrillo-Reid et al.,
Thanks for sharing this preprint on bioRxiv, it is a very interesting read! I have one quick question for you.
As a main asset of your method, you describe that it offers advantages compared to more established methods based e.g. on cross-correlation or mutual information. I think it would be good idea to test this directly. One way to do so (the following is probably not the best way to test this!) would be to use e.g. a correlation matrix of neuronal activities and sum over the columns to get an approximative measure of the respective "neuron's node strength"; and also correlate this neuron's activity with the visual stimuli to get the neuron's predictive performance. Then you could select a cortical core ensemble as in Fig. 2D also based on model-free cross-correlation measures (or something similar) using the two dimensions "node strength" and "predictive performance", which would allow to compare the ensembles selected by the CRF-based selection process and the ones based on a model-free procedure. Right now, the ensembles selected using your method is compared to randomly selected ensembles, but a comparison with ensembles selected using a model-free approach would be much more informative, if I am not mistaken.
Or any other more direct comparison with model-free methods would be really appreciated and would help to better understand the usefulness of the presented method.
I hope that I did understand your method correctly and that you find my comments helpful.

Exploration of these interactive plots shows that it takes a great deal of cherry picking of parameter combinations to put any plausibly infectable hosts at the top of the list of species whose mitochondrial material is most correlated with the abundance of SARS-CoV-2.
I am curious what parameter combinations were attempted and how reasonable it is to call them "cherry picking." Sampling on 1/Jan was biased to locations known to be linked to humans recently infected with SARS-CoV-2 and is expected to show correlation between SARS-CoV-2 RNA and nucleic acids from both humans and species sold at these locations.
Sampling on 12/Jan was biased towards locations known to be linked to wildlife sales without, as far as I know, reason to expect a positive SARS-CoV-2 result by PCR or sequencing.
In my hands, the only "cherry picking" that is required is including samples negative for SARS-CoV-2 and not including sampling from 1/Jan when it was focused on locations of human COVID-19 cases. The result is that samples with reads for "Amur hedgehog" and "Malayan porcupine" consistently rank highly with any choice of parameters otherwise. This is also true if examining correlation between species reads and positivity by PCR.
It is difficult to say it's "cherry picking" to focus on the one day with sampling not biased to locations expected to have reads mapping to SARS-CoV-2. However, I agree with comments by Débarre and Crits-Cristoph that this type of correlation analysis is problematic. In the end, in pointing to multiple species it points to one location. That location and locations and animal carcasses linked to it were subsequently sampled hundreds of times, so clearly investigators saw correlation in this data and acted on it.

We at the Evolutionary Health Group ( https://evoheal.github.io/) "https://evoheal.github.io/)") really enjoyed this paper.
Here are our highlights:
This work models viral adaptation not as isolated mutations but as evolutionary escape trajectories constrained by both protein viability and antibody pressure. The authors show that escape proceeds through narrow and predictable “escape funnels”, consistent with convergent mutations observed in SARS-CoV-2 variants.
Combining generative RBM models with mean-field trajectory analysis enables quantitative estimates of path entropy and fitness cost. The model captures the direction of antigenic drift and enables prospective prediction of antibody escape, including for therapeutic cocktails: anti-correlated escape profiles force viruses onto longer, costlier routes.
The model shows impressive predictive power. It demonstrates that, despite the potentially vast mutational landscape, the virus tends to follow a limited set of evolutionary routes, many of which are already observed in Omicron variants.
The approach is broadly applicable and offers a principled route to rational therapeutic design for rapidly evolving pathogens - for instance, for HIV and influenza.

Some random thoughts from journal club today:
Overall we thought this was a cool experimental approach to ask some neat questions about inbreeding depression. We're also big fans of the nematode system in that it is both fast and tractable while still being a "real" diploid organism. We did have some places where we were a bit confused or thought things could be clearer, however:
Perhaps we missed it, but would be nice to mention that E464 is a single isofemale line. People were initially very confused by the SFS in Figure 5.
The X-chromosome arguments confused us. Our a priori thought was that selection in natural pops should zap any recessive deleterious variants on the X because males are hemizygous, so that should allow for rapid homozygosity on the X during inbreeding. A bit more depth here explaining the thinking about why we might expect otherwise would help.
We didn't buy the argument (on line 507) that inbreeding == environmental change. This might be true under a scenario in which there is no standing genetic variation, but seems unlikely to be true for an outcrossing population.
It was not clear to us how differences in dominance in MA lines vs natural pops (L440) translates to effect sizes (L445). Is this assuming a correlation between dominance and effect size?
It seemed to us that, given the small size of the genome, population, and number of generations, there was a lost opportunity to compare the results to simulations. Seems like either simulations in something like SLIM or even simulations using the allele freqs in the Ancestor could have been useful to get a better idea of expectations. In several places (e.g. paragraph starting L335) having some expectations of what we think should happen would have been helpful. For example, while impressive, the simple 0.5^X generations of inbreeding expectation (L317) is not particularly realistic given linkage.
I liked the discussion of mating system, especially how trans polymorphisms are harder to select on in an outcrosser. But given that the experiment started with an isofemale line that was then inbred, these don't seem that important here (as you note at the end of the paragraph). I'd be tempted to axe this paragraph.
Fig4 parts C-E look awfully similar because of the huge peak at 0. Why not separate into %polymorphic and the SFS of polymorphic?
Fig5 Needs more explanation and/or redoing. It took us a while to figure out what the lines were, and our interpretation is that runs of homozygosity are literally the white space between lines? Why not make a histogram of the number of ROH in a given window size along the genome? Or the cumulative distribution of ROH as you move along the genome?
Figure 6/7 could benefit from having some expectation of 1) how many SNPs should follow each pattern and 2) how likely the changes in allele frequency are. Both could be achieved (I think) by some simualtions.
L448 Given the known high nucleotide diversity in remanei, it seems like there is a strong a priori expectation that you'd have a lot more mutations than in an MA experiment.
L41 We were confused by this. Our intuition was that larger mutational target size = more sites = higher input of new mutations. Why does a larger mutational target size lead to a limitation of new mutations?
L481: the phrase "positive directional selection" confused some folks. I think "fitness" would be clearer.
L433 and L448 both purport to explain the most likely explanation.
L119 Would clarify to say these are MA lines. This is made clear later on, but I initially thought "populations" meant natural or experimental populations, not MA lines.

Study by Ghosh et al indicates the role of lysosome as a player of MHV egress. As per data presented in the study, viruses enter the ER-secretory pathway, proceed to Golgi and then gets shuttled back to lysosomes for release. Simultaneous with its participation in virus release, deacidification of the lysosomal milieu has been demonstrated to hamper the antigenic presentation via MHC-dependent antigenic presentation hence dampening the immune response against beta-coronavirus. It would be interesting to investigate whether viral entry from ER-secretory pathway to lysosome is directly associated with the deacidification of lysosomes, or at earlier time points (6hpi, 9hpi) deacidification already gets started as a result of virus-mediated activation/deactivation of host signaling thus setting up a platform for virus egress.

An exhaustive analysis of viral diversity in blackflies collected from Onchocerciasis-endemic areas is presented. While it provides valuable data, the study has limitations that affect the coherence between its main objective and results. The title and introduction suggest a focus on neurotropic viruses associated with epilepsy linked to Onchocerca volvulus (OAE), but the results primarily describe viral diversity without providing evidence of these viruses. Possible explanations for the absence of neurotropic viruses are not discussed, nor are methodological alternatives proposed to address this issue. To improve the narrative, it is recommended to reframe the title and present the work as an exploratory study on viral diversity in blackflies.
Methodologically, the sample size (10 blackflies per pool) and the lack of information about the genus of the collected blackflies compromise the representativeness of the data. Additionally, the criteria for excluding incomplete sequences are inconsistent, as incomplete Riboviria sequences were retained, potentially biasing abundance results.
Regarding the figures, Figure 2 lacks a clear description of its columns, hindering interpretation. Figure 3 presents phylogenetic trees with barely distinguishable details, complicating analysis. In Figure 4, the point corresponding to Blackfly flavivirus does not clearly cluster with invertebrate hosts, weakening conclusions about its specificity. Analyses based on PCA and dinucleotide composition are interesting but insufficient to infer viral tropism without experimental validation. The supplementary files, although relevant, lack proper descriptions, and the main text does not specify which supplementary figure to consult, limiting their utility.
Although the study does not successfully address its main objective, it provides an important starting point for future research on the viral diversity of blackflies and highlights the need for further investigation into their relationship with human diseases in endemic areas.

In particular, I believe that pCFD5 plasmid for expressing multiple gRNAs will be very useful to many in the field, as well as the ability to do tissue-specific knock-outs using the UAS:gRNA plasmid. I hope that such robust tissue-specific knockouts are generally applicable for other genes.
I was also happy to see that Port & Bullock published their work on the Cpf1 system, showing that while it is functional in flies, it does not appear to be quite as robust as Cas9, and has a relatively high failure rate (which I have also observed myself).

As our manuscript was under review and ultimately accepted in the meantime (https://rdcu.be/drgAc) "https://rdcu.be/drgAc)"), we did not manage to address all the issues you mentioned for the peer-reviewed version.
With respect to PC vs NMDS: we have adopted the method of doing both analysis since PC plots are limited to two variables in each iteration and this can cause statistical limitations with smaller sample sizes (as is the case here). NMDS collapses the variability to two dimensions and does not assume normal distribution. We use these two analyses in a complementary manner (one does not influence the outcome of the other, they are two independent methods). As our interest here was limited to inspect if the data is powerful enough to distinguish expression patterns at the respective time points, we did not focus on further discussion of these tests.
With respect to identifying secreted proteins, we used SignalP5 and TMHMM to identify candidate secreted soluble proteins. This was only mentioned int he methods section and we could have added this in the results section, as well.
We used the pipeline detailed in Figure 4 to identify the transcripts as noncoding. The tool CPC with a cutoff of an ORF length of 200 bp was used for that.

Chung et al. (2024) identified a physical interaction between ERC1 and ATG8e, leading them to explore potential ATG8-interaction motifs (AIMs) in ERC1. Using the iLIR database (Jacomin et al., 2016) for AIM prediction, they found the results irrelevant to the ERC1-ATG8e interaction, indicating a false prediction. Through truncated ERC1 variants, they identified a non-canonical AIM undetectable by current prediction tools, which focus on the canonical [W/F/Y]-[X]-[X]-[L/I/V] sequence. They validated this motif with AlphaFold2-multimer (AFM), a method we previously demonstrated (Ibrahim et al., 2023) to accurately predict non-canonical AIMs, as shown with ATG3.

Since there is a lot of debate about whether clathrin plaques/ flat lattices are artefacts of interactions with the coverslip, it would be interesting to see the dynamic lifetimes of plaque vs. pit assembly, and whether they are, at least in part, specific to coverslip facing surfaces. The authors have previously used diSPIMs to observe clathrin and EGFRs (10.1016/j.bpj.2018.11.545). Do they observe distinct modes of clathrin assembly in both coverslip facing and dorsal free surface of the cell? That would be crucial to absolve the clathrin flat lattices of being artefacts. They may be specific to cell-cell adhesion, dependent on alternative splicing. That concept again, needs further experimentation and is probably best done in live organisms as demonstrated by Kirchhausen.

This pre-print by Robert C. Edgar has the intention to measure differences in the<br /> taxonomic framework of ribosomal RNA databases. For this purpose, he compares<br /> the taxonomic annotations and guide trees of the SILVA, Greengenes and RDP<br /> databases to estimate their annotation error rates. His results show that<br /> overall RDP has an error rate of 10-15% while SILVA and Greengenes both have<br /> 17% (page 2 and 21). He claims that the better performance of RDP vs. SILVA and<br /> Greengenes is due to the fact that RDP uses a fully-automated annotation system<br /> while SILVA and Greengenes are based on a semi-automated procedure involving<br /> manual curation by taxonomic experts (page 21).
First, with respect to the SILVA database there are a couple of errors in the paper:
Page: 9:<br /> SILVA is not only based on LPSN but, like RDP, uses the Bergey’s Manual as the<br /> main source of taxonomy (see https://academic.oup.com/na... and https://www.arb-silva.de/do... "https://www.arb-silva.de/documentation/silva-taxonomy/)"). The SILVA team is even an<br /> associate member of Bergey’s Trust https://www.bergeys.org/tru... and well informed about any upcoming changes in taxonomy.
Page 11: Edgar implies that only for RDP the history of genesis of the datasets is available. This is not true since also SILVA provides all datasets and guide trees back to<br /> 2015 in its archive on the website https://www.arb-silva.de/do....
Second, it is questionable if the comparison as it is presented are justified. The general<br /> idea of comparing taxonomic frameworks is not new and the SILVA team has<br /> already made attempts to quantify and eliminate them see https://academic.oup.com/na.... It is also a general misconception<br /> that we know the “true gene/phylogenetic tree” as stated on page 5, 13, 14 and<br /> 20. Consequently it is impossible to give a clear answer what is correct and<br /> what is wrong with respect to different taxonomic annotations. Taxonomy is<br /> never static, but rather a moving target influenced by the constant insertion<br /> of new sequences in the tree as well as substantially faster the tree<br /> calculation algorithms that allow to reconstruct trees with many more<br /> sequences. Consequently, for each SILVA release the SILVA team spends a<br /> significant amount of time to manually go through the guide tree to provide the<br /> best compromise between the phylogenetic tree and taxonomy. A guideline<br /> describing the “technical” problems in phylogenetic inference has even been<br /> published by the SILVA team in 2008 see https://doi.org/10.1016/j.s....
Keeping this in mind that taxonomy is not necessarily monophyly and any reconstructed<br /> tree is just an approximation of the “true tree” it is rather the rule than the<br /> exception to locate differences in the taxonomic annotations between databases.<br /> Recalling this, the added value of taking the five years old Greengenes<br /> annotations into account for the comparisons can be questioned. If a comparison<br /> is necessary, it would make more sense to correlate the intraspecific<br /> differences of the guide trees over time with the interspecific differences<br /> between the three annotations. My best guess would be that the changes in<br /> taxonomy over time are almost in the same range as the differences between RDP,<br /> Greengenes and SILVA.
In summary the results provided are neither new nor unexpected. It is even a feature of<br /> the three databases to provide different views on the “true tree” of life.

My name is Blake Williams and I am an undergraduate student in the Biomedical Research Minor at UCLA.

We all appreciated how thorough and well-designed these experiments were, the claims made in the paper were all supported by multiple strong lines of evidence. As my group and I read the paper, we had a few suggestions to share with you.
In Figure 2B, protein abundance of the kidney derived and brain derived pre-pro-vasopressin would have been helpful to quantitatively compare the vasopressin levels from each organ.
In Figure 4, I would have appreciated some quantitative analysis of the amount of colocalized Rab3 and pre-pro-vasopressin relative to pre-pro-vasopressin on its own in order to compare the difference between the basolateral, mid-section, and apical levels of the IMCDs.
The methods used in Figure 5 were very creative and the results were compelling and interesting to read!
A figure legend or explanation of the 5 different wells in the Western blot conducted in Figure 8A would make these data more clear.
On a broader scale, I think this paper would be strengthened with a more thorough examination of pre-pro-vasopressin made in human kidneys. The sequence of mature vasopressin is the same between humans and mice, so the same assay used in Figure 5 could also be used to detect if vasopressin synthesized by human kidneys is also active. Additionally, using female mice in addition to male mice would increase the power and scope of these experiments.
I’m excited to see future studies on this topic and the physiological impact and relevance of kidney-derived vasopressin! Looking forward to reading more work from your lab!

So that is pretty consistent with the findings here I think.

I have only a doubt, concerning the retrieval of bacteria other than endobacteria in your spore. As you may know, we have retrieved many bacteria strictly associated with AMF spores (after 15 washings). Actually, you performed a de-contamination of spores, with H2O2 and chloramine T, so you assumed that the retrieved bacteria were endobacteria. As our previous works described the occurrence of bacteria within the different layers of spore walls, I wonder whether they may have been protected from de-contaminating agents in such a peculiar niche. This is why we defined them as "stricty associated". With all my best wishes and regards, Manuela Giovannetti

This paper was the subject of the Miller lab weekly journal club and, following a fun discussion of the findings, we have the following comments to make. Please bear in mind that we do not study mRNA regulation or decay, but enjoyed reading the manuscript which was somewhat out of our normal area of expertise.
This paper uses a synthetic mRNA library to examine how changes in a 10 nucleotide sequence preceding an upstream open reading frame (uORF) can alter translation and mRNA stability of both the uORF and downstream ORF. The main findings are that translation of the main ORF is protective to the mRNA, whereas improved translation of the uORF is detrimental to the stability of the mRNA. Additionally, sequences are found that prevent translation entirely, whilst others are shown to enable cap-independent translation of the main ORF. Finally, the degradation pathways that these types of messages might follow are identified. Overall, this seems a powerful tool to study the sequence landscape that is possible for modulating uORF and ORF translation and the effects on subsequent mRNA decay. We were excited to think about how the information in this study could be mapped onto the human genome to understand how frequent the different classes of modulatory sequences are and whether any of these have actually been selected for in evolution (one example, that of an RG4 upstream of NRAS is an exciting first step for this!).
We have some short points of note following our group discussion:
The text relating to Fig 1b states that there is a reciprocal relationship between tracer peptide (uORF) and GFP (main ORF) abundance (ie. if tracer peptide is translated, GFP is not). This relationship wasn’t apparent to our eyes in the flow cytometry of Fig 1b, which showed that with the AUG condition, increased tracer peptide was generally accompanied by increased GFP. This is probably due to the plasmid-based system used for expression, since in Supplemental Figure 1b. that used RNA transfection, the effect was clear. We spent quite some time puzzling over this (and some of the other flow cytometry plots), so for a naive reader, additional explanation here might be good.
In some experiments presented as violin plots (eg. Figure 2B and C), n is clearly very large and the p-value presented is impressive, but we wondered if it would be more useful to plot effect size rather than p-value for these data. With such large datasets, effect size can be more meaningful in understanding how two populations vary. On a similar note, we thought it would be valuable to include the p-values (and effect size) for the in vitro comparisons of mRNA stability to support the claim that the stability is only different between the populations in vivo.
Finally, on a stylistic note, we felt that there was a lot of important data in the supplementary figures, in particular the various experiments that follow up on the potential decay mechanisms for these reporters. The short format does not do justice to the full story!
Thank you for sharing your work on BioRXiv and we hope our comments might be useful

It seems like an important aspect of this is that you are getting a much more nuanced picture of water use. I agree that this will be relevant for efforts to predict water use responses to the environment. I'm wondering if you could include some discussion about other efforts to do this (e.g., with time lags, etc.). I think that this will provide definite mechanistic improvements, but it seems like relevant literature to discuss.
Also, I like how you used light sensors for individual leaves. I wonder how many hysteresis analyses use light data that is not representative of the canopy. I would imagine that most light sensors are either on the ground or on top of a tall tower (above canopy), which could be biased indices of what a tree actually experiences. What are the implications of this 1:1 (sap flow to light) connection (and its potential absence in other studies) for your findings?

Reviewer #3 (Minor Comments):
P2, ?3. The authors cite To et al. (2011) for the claim that foveal magnification is greater than peripheral magnification. However, to make this claim, To et al. rely on a number of other citations which would be more appropriate here (?2 of their introduction). A clear example of this is Horton and Hoyt (1991). Additionally, it might be more appropriate to describe cortical magnification as having units of square-mm/square-degree rather than only mm/degree. <br /> We appreciate reviewer 3 for her/his suggestion, we cited Horton and Hoyt, 1991; Azzopardi and Cowey 1993 in the third paragraph of Introduction on Page 3.
P2, ?3. Additionally, the final line of this paragraph addresses receptive field size. It might be of interest to review the finding of Harvey and Dumuolin (2011) [10.1523/JNEUROSCI.2572-11.2011], that the product of the pRF size and the cortical magnification factor are approximately constant across human V1 and nearby visual cortex. <br /> We added the information regarding how receptive field size and cortical magnification factor changes as eccentricity increases through V1 constantly in human V1 and near visual areas in the third paragraph of Introduction on Page 3.
P4, continued ?1. in order to understand what the FEF's inclusion in the Dorsal Attention Network means, it might be useful to introduce the Dorsal Attention Network briefly when discussing the DMN and the FPN. <br /> This sentence was reworded for clarity, including removing reference to the Dorsal Attention Network since it was not relevant to the sentence’s main point.
P4, full ?1. Given the amount of work that has been done on the fronto-occipital and inferior longitudinal fasciculi, the following sentence should probably include a citation or three. "Major white matter tracts that connect to the occipital lobe such as the inferior fronto-occipital fasciculus (connects occipital lobe to lateral prefrontal cortex) and the inferior longitudinal fasciculus (connects occipital lobe to anterior temporal lobe) have been well documented using tractography methods in humans." <br /> We have added this citation to the text in the introduction: “Major white matter tracts that connect to the occipital lobe such as the inferior fronto-occipital fasciculus (connects occipital lobe to lateral prefrontal cortex) and the inferior longitudinal fasciculus (connects occipital lobe to anterior temporal lobe) have been well documented using tractography methods in humans (Wu et al., 2016).” <br /> Here is the full citation: Wu, Y., Sun, D., Wang, Y., & Wang, Y. (2016). Subcomponents and Connectivity of the Inferior Fronto-Occipital Fasciculus Revealed by Diffusion Spectrum Imaging Fiber Tracking. Frontiers in Neuroanatomy, 10, 88.
P4, full ?2. This paragraph is a bit hard to follow and might be improved by breaking it up into shorter sentences. In particular, I'm not 100% sure what the authors mean by "direct and indirect structural connections". Additionally, I'm not sure why the end of this sentence follows from its beginning: "Since functional connectivity between two brain regions could come from both direct and indirect structural connections, we used DWI to examine direct connections between regions (Adachi et al., 2012; Honey et al., 2009) that were previously found to show functional connections." <br /> We have changed the wording of this paragraph to the following:<br /> “The goals of the current study are 1) to assess the reproducibility and generalizability of retinotopic effects on functional connections between V1 and functional networks that were found in prior work (Griffis et al., 2017). We aim to extend these findings in a new dataset collected under different task conditions (previous work used blocks of rest during a task with central fixation and the current data was collected as part of a resting-state only scan). 2) Extend prior work on the retinotopic connectivity difference to structural connections between V1 and functional networks. 3) Examine the relationship between functional and structural connections. Since functional connectivity between two brain regions could be derived from measurable structural connections, we used DWI to examine connections between regions (Adachi et al., 2012; Honey et al., 2009).”
P4, full ?3. Again, the concept of a "direct connection" versus an "indirect connection" appears prior to being introduced. Given that this paragraph marks the concept as critical to the point of the paper, the introduction needs to explain what these are. Additionally, it seems that the paper separates the idea of a direct/indirect "structural connection" from that of a direct/indirect "functional connection". This should all be clearer. <br /> In addition to the text added in response to the above comment the following text has been added to the paragraph referenced in this comment: “the pattern of structural and functional connections is similar, suggesting that this lateral frontal functional connection pattern arises from a direct (uni-synaptic) structural connection.” for additional clarification.
P6, ?3. "Previous work has shown that cortical anatomy is a reliable predictor of the retinotopic organization of V1 (O. Hinds et al., 2009; O. P. Hinds et al., 2008) so that the more posterior parts of the visual cortex represent more central portions of the visual field." At the risk of splitting hairs, the publications by Oliver Hinds show mainly that the V1 *boundaries* are reliably predicted by anatomy. A better citation for the V1 *retinotopic organization* is Benson et al. (2012) [10.1016/j.cub.2012.09.014], wherein we actually assessed the retinotopic maps and not just the boundaries. <br /> This citation has been added.
P6, ?3. "The average eccentricity of each segment was estimated from Benson and colleagues' probabilistic retinotopy template (Benson et al., 2012)..." The correct citation for the retinotopic template is Benson et al. (2014) [10.1371/journal.pcbi.1003538], along with Benson and Winawer (2018) [10.7554/eLife.40224] assuming you are using a recent version of the template, which appears to be the case based on Figure 2 (though given that you are using the FreeSurfer V1 boundary also, I can't really tell). Additionally, it isn't technically correct to call this a probabilistic template (such as might be said correctly of the visual area atlas by Wang et al., 2015). The retinotopic template is more accurately a model of retinotopic organization fit to the average retinotopic organization across many subjects-it does not explicitly express or depend on probabilities. <br /> Wording has been changed to retinotopic template.
P6, ?3. "These ROIs were defined in the gray matter on the cortical sheet for the freesurfer template, then moved into the individual anatomical space for each participant." I believe that the authors' intent here is to state that ROIs were defined on FreeSurfer's fsaverage brain using the eccentricity of the retinotopic template (which is also defined on the fsaverage brain) then were interpolated over to individual subject cortical surfaces using FreeSurfer's anatomical registration. However, I don't have a good prior for what the "freesurfer template" is here or what the "gray matter on the cortical sheet" of it might be, so this may all be wrong. Perhaps the implication is that the ROIs were hand-drawn in the voxels of the fsaverage subject's "ribbon," but if so, is the interpolation back to the individual subject done on the surface or using FreeSurfer's newish diffeomorphic volumetric alignment? <br /> The following text has been revised to further clarify for the reviewer: “These V1 eccentricity segment ROIs were defined on FreeSurfer's fsaverage brain using the eccentricity of the retinotopic template then were interpolated to individual subject cortical surfaces using FreeSurfer's anatomical registration. To avoid the potential for artifacts due to differences in ROI size when comparing probabilistic tractography results, the number of vertices were kept similar (on the Freesurfer fsaverage brain) between eccentricity segments.”
P6, ?3. "To avoid the potential for artifacts due to differences in ROI size, the number of segments per eccentricity region were assigned to more evenly distribute ROI size." Again, this is not at all clear. Earlier text in this paragraph implies that the segments *are* eccentricity regions. Does this sentence indicate that the segments were adjusted in each individual subject to be of a similar size? Or that the ROIs were split into several segments each before interpolation? Is there a material difference between what was done and simply starting with a larger number of segments? It's not clear to my why the process is described in terms of three segments whose eccentricities are reported then redescribed in terms of more segments whose eccentricities are not reported. <br /> We acknowledge that the reporting of the V1 ROI eccentricity segments was unclear. We have simplified the text to be more clear so that it now reads: “Based on this template, 3 retinotopic regions were identified: central vision (mean eccentricity estimates of 0-2.2 degrees visual angle), mid-peripheral vision (mean eccentricity estimates of 4.1-7.3 degrees visual angle) and far-peripheral vision (mean eccentricity estimates of 14.1-25.5 degrees visual angle) (Figure 2).”
P7, ?1. "... voxels within the white matter corresponding to the network ROIs were used as track seeds." I found this initially confusing as immediately prior to this section, "ROI" refers to the ROIs of V1, which should have no truck with the white-matter (i.e., a white-matter voxel predicted to be in an ROI derived from the FreeSurfer's V1 label or the retinotopic template must by definition be erroneous). However, I suspect that this is intended to be about a separate set of network ROIs? This should be clearer. <br /> Yes, there are two sets of ROIs, the V1 ROIs and the Network ROIs. The “network ROIs” has been changed to “network-ROIs” to emphasize this point further. Also, whenever the term “ROI” is used, the name of the set of ROIs being referred to is now stated.
P7, Data Analysis. Again, citing the analysis methods is well and good, but this section should make very clear up front which data were collected/analyzed by the authors and which data were collected/analyzed by the HCP. I should be able to easily tell both what analysis steps were performed *and* which set of authors performed each step. <br /> See response to Reviewer #3 Major Comment #2.
P7, ?2. "Next, right-to-left and left-to-right acquisitions were concatenated into a single 4D volume for the functional connectivity analysis." While I understand from this sentence that the preprocessed images were transformed into single 4D volume files, I do not follow the significance of "right-to-left" and "left-to-right" in this context. <br /> The text of the article has been changed to clarify this: “Next, both the acquisitions (those collected right-to-left and those collected left-to-right) were concatenated into a single 4D volume for the functional connectivity analysis.”
P8, ?4. The text references a "2mm2 Gaussian kernel". Is this supposed to be 2 mm (not squared)? If so, does it refer to the FWHM or to the HWHM or to the parameter ?? It says the "surface maps" were smoothed, but was this done on the FreeSurfer cortical sphere (in which case, mm is a curious unit)? Volumetrically? Something else? <br /> This was a typo it has been changed to “2mm” and the text now reads “Surface maps of the track termination probabilities were smoothed using a 2mm FWHM Gaussian filter and averaged across all subjects.”. This was done with mri_glmfit “fwhm” flag.
P9, ?1. More information is needed about the t-tests that were used. Were these tests one-tailed or two-tailed? Corrected for multiple comparisons or not? How was mri_glmfit used to perform these tests? The help-file for mri_glmfit mentions t-tests only in the context that a certain use-case reduces to a t-test in some circumstances. <br /> We have added “two-tailed” to the text. The mri_glmfit function can be used as a t-test under one sample group mean test with the --osgm flag. We did not correct for multiple comparisons due to the analysis’s design with specific, planned comparisons.
P9, Comparison of Functional and Structural Connectivity. Was only one correlation coefficient calculated? Were the authors not interested in these correlations for the non-central V1 regions? It seems irregular that only one of these would be examined given the experimental setup and the hypotheses of the manuscript. <br /> We have now included dice coefficients, per the reviewer’s suggestion, as well as adding non-central V1 regions in this new analysis.
Methods, generally. In a couple of places, the authors refer to commands like "mri_vol2surf" (P8, ?1). It would be ideal if the command lines or scripts were also provided with the manuscript. <br /> The code has now been added to the code repository.
P9, ?4. "The t-test comparing functional connectivity to different eccentricity segments in V1 revealed significant effects (p<.001) and brain regions belonging to FP, CO, and DMN functional networks (Figure 3)" is the "and" here supposed to be "in"? <br /> This edit has been made.
P9, ?4. It's not clear to me how "preference" was evaluated here. For example, "central representing V1 was preferentially connected (over mid-peripheral and far-peripheral V1) to regions associated with the FP network". Was this assessed by visual inspection? A good quantitative metric would be nice to have here, such as the dice coefficient for each ROI-network pair. <br /> We have added dice coefficients to the analysis. See Tables 1 & 2.
P9, ?4. "Those previous results had also shown differences in connectivity between mid-peripheral-representing regions and far-peripheral representing regions, which were not observed here, (Figure 3)" <br /> This text has been reworded for clarity: “However our results differ in that mid-peripheral-representing regions and far-peripheral representing regions differences were not observed here (Figure 3).”
P10, Figure 3. "There, vertices in yellow showed stronger (z>3) connectivity to central V1 than to both Far peripheral and mid-peripheral regions." I do not understand the significance of "(z>3)" in this caption. Additionally, what is the significance of the gray color shown on all brains in the bottom row? <br /> Clarification has been added to the Figure legend, including “The grey regions indicate the location of the other networks.”
P11, ?1. "... we performed pairwise comparisons of functional connections... Results indicate that ... there are preferential connections between central V1 ..." Again, I'm not clear how preference is being assessed here, or what is being compared pairwise. Pairwise comparisons between segments and networks? What values exactly were compared? If these are referring to visual inspection, that is fine, but the language seems to suggest something more programatic, and what that might be is not clear. <br /> The text has been clarified to now state “We performed statistical comparisons (t-test) of functional connections between central vs far-peripheral eccentricity segments of V1 and the FPN (Figure 4).”
P11, Figure 4. Please tell us what exactly is being plotted. What value minus what value? <br /> The values being subtracted have now been added to all figures.
P14, ?2. "A comparison between structure and function showed overall agreement, indicating that the functional connections are likely mediated by direct structural connections (Figure 6, right column)." Depending on what the authors mean by "mediate" I'm not sure that this follows. Please elaborate. <br /> We acknowledge that this wording is unclear. We have therefore changed the wording of this statement to the following: “These relationships indicate that the overall pattern of connectivity of central V1 greater than far peripheral V1 is consistent across modalities with an especially high overlap within the FPN.”
P14, Figure 6. "Far-peripheral and central V1 are statistically different within the FPN..." How was statistical difference within the FPN assessed? <br /> Please refer to the following section:<br /> “Tractography Analysis <br /> To test the hypothesis that patterns of functional connections previously found in V1 (Griffis et al., 2017) are similar to patterns of structural connections, comparisons were made between the central and far-peripheral eccentricity segments of V1 connectivity patterns to the FPN. Differences in track probabilities corresponding to V1 eccentricity segments connections were compared by paired, two-tailed t-test (using Freesurfer’s mri_glmfit with a one sample group mean test). “
Style/Aesthetic Comments <br /> Throughout the manuscript, starting on P3, full ?1, there are several mismatched parentheses that are distracting. These typically look like this: "some claim is made here (e.g., (Someone et al., 2010) then continues here". Almost all of these could be fixed by removing the "(e.g. ". That said, the use of "e.g., "makes me think that there are other citations that *should* appear here, but haven't been filled in yet, especially given that many of these are broad statements somewhat outside my particular expertise, such as "The fronto-parietal network (FPN) directs attentional control (e.g., (Zanto & Gazzaley, 2013)".
P4, L8. "Markov et. al," should be "Markov et al.," <br /> This edit has been made.
P4, full ?2-3. The authors mix the style "Something listable: (1) first thing, (2) second thing..." and the style "Something listable: 1) first thing, 2) second thing." <br /> This formatting has been changed.
P7, ?1. The acronyms "FP" and "CO" were previously reported as "FPN" and "CON". This needs to be fixed throughout. I get that at times the intention is to represent the deduplication of the word "network," i.e., "the fronto-parietal and default mode network" becomes "the FP and DMN". I think this usage is less clear to readers than "the FPN and DMN" and, besides, the text sometimes says "the FP and DMN networks" (P8?3L3, P9?4L4). Alternately, introduce FP et al. as separate acronyms on P7: "Fronto-parietal (FP), cingulo-opercular (CO), and default mode (DM) networks...". <br /> Abbreviations have been edited for consistency.
Reviewer #3 (Additional data files and statistical comments):
As mentioned in the Major and Minor comments, most if not all of the statistical tests need to be more explicitly described. I could not currently reproduce the exact tests from the manuscript, even if I had the data.
Additionally, because the project is a reanalysis of a large dataset, it would be particularly valuable to have the source code used for analysis. It is nearly impossible to reproduce or assess a project like this without such code.
The code for the analysis has now been added to a repository and it is referenced in the paper.

Thank you for this paper. It does a nice job of demonstrating that priming effect is in the eye of the beholder. We read it for journal club today, and I am summarizing some comments and suggestions we came up with, primarily related to the display of the data. This is because the objective set out for the paper (see if bacteria can grow on NOM) is not in line with much of the introduction, experimental design, or interpretation of the results. We suggest 1. see if bacteria grow on NOM, and 2. how the presence of LOM affects this. Figure 1 should then be just NOM minus C-free controls, and a separate figure for just the composite and mix samples were plotted (as figure 2). Even better, just plot the priming effect through time by subtracting the composite from the mix. At present, figure 1 is complete information overload, and making everything divided by or subtracted from some control will go a long way to remedying this. And hopefully also getting rid of the ANOVA tables. We would also suggest plotting the respiration data as a rate rather than cumulative respiration to enable figure 1 and 2 to be viewed more comparably could also be useful.
A strength of your paper is that it shows that whether priming effect exists depends on whether you look at respiration or growth. However, what we are usually interested in when we think of priming is how much of the native organic matter will be lost. If you have any measures of the remaining LOM or NOM to indicate whether more was lost overall under priming, this would be a great addition. Including in particular LOM data from the different components to show if the crash and burn growth was a response to depleting the LOM or whether LOM became limiting would also be very useful in interpreting the priming results.
Finally, a strong theoretical basis for why time matters for priming effect is much needed; is a priming effect real if it is not consistent? What does it mean? How does growing the cells on acetate and then switching them to NOM affect results compared to another source? Do bacteria undergo batch culture in estuaries, or is it more like chemostats? Physiology is very different during different growth phases and this may ultimately change the conclusions made in the paper.

For example, previous reports (e.g. https://dx.doi.org/10.3390%... "https://dx.doi.org/10.3390%2Fcells9020458)") suggest that some non-canonical splice sites could be due to annotation of genes on the opposite strand.

Something you might want to keep in mind: it is not logical to compare this algorithm to Seurat 3 because Seurat 3 is not intended for deconvolving mixtures, rather it provides cell type enrichment scores to "deconvolve" capture spots.

The final version of this paper is in Gene Reports 8, 45-48. I was somewhat surprised to see that the “pregenomics era” refers only to the last two decades. But entire genomic sequences, often from viruses, became available much earlier. Furthermore, Grantham made enormous strides in the 1970s and 1980s with his first database of sequences that preceded the emergence of GenBank. Many of Grantham’s sequences were incomplete, but you do not need an entire dictionary to work out how a dictionary functions! Tear out a page and that suffices! So just because we now have more entire genomic sequences, does not mean that the former era was “pregenomic.”
The paper states: “Since position 3 is not constrained by the amino acid frequencies, it is the best reflection of selection pressure in mRNA interaction dynamics. If the Politeness Hypothesis were true, position 3 should have been the major contribution of the purine rich pattern of mRNAs, but actually its average purine content is less than 50% in most species.” In fact, third positions have to respond to numerous non-amino acid pressures other than that of purine-loading (RNY-pressure, GC pressure, etc. ), so it is not the best reflection of selection pressure on mRNA interaction dynamics (see: http://post.queensu.ca/~for... ).

Dear Willems et al, this preprint was discussed in a lab meeting and we would like to offer the following for review. Thank you for posting this very interesting manuscript. Best, The Sanchez Lab:
The manuscript by Willems et al. presents an overview of a new software, AlphaTims, which allows for fast indexing and retrieval of LC-TIMS-MS/MS data. The authors present a clear explanation of how software indexing and data matrix construction works, along with an example of how their software is used to simplify the accession of data from complex samples. This open-source program has the potential to make data more accessible without proprietary software, and has many possible applications in conjunction with further data processing software. Overall, AlphaTims looks to be an impressive piece of software, and figure 1 especially did a great job of visualizing and explaining the difficult concept of data indexing in 4 dimensions. This was a great, polished read, and very informative in elucidating the experimental process for those who are less familiar with the LC-TIMS-MS/MS workflow. It was also appreciated that the data was publicly available on PRIDE! Below please find a list of critiques that may improve the accessibility of some of the concepts and better illustrate the software’s utility.
? Figure 1 is very well done and all the terms are well-explained. It may add further clarity if the authors were to add a part (d) to help visualize what the data looks like once indexed, perhaps with number values. Additionally, the color palette is difficult to interpret when printed in black and white; the authors may wish to consult ColorBrewer.
? Some of the data on the speed of the software is difficult to conceptualize without benchmark data for comparison. There’s a brief comparison between the program and Bruker’s DataAnalysis on two different systems (one local and one Github VM) with different specifications, which doesn’t provide a lot of context as these do not seem to be directly comparable. While the speed of the software compared to others is not necessarily a major focal point, as AlphaTIMS carries out different processes to DataAnalysis, it’s still a little difficult to conceptualize the relevance of the times in figure 2, as these events are somewhat decontextualized. With that being said, it was apparent that both systems used solid state drives. Therefore, even if runtimes cannot be directly compared, it may be helpful to note whether the code is CPU-bound, storage speed bound, etc. and suggest what hardware upgrades may help increase performance.
? The documentation in general is very good! The accessibility and the included explanations for all of AlphaTims’ reading, writing, slicing, and visualization workflows are impressive. However, more examples for other included processing functions (i.e. centroiding) would be helpful.
? Some more broad data visualizations in figures 3 and 4 would be helpful. Seeing an overall LC-MS and/or TIMS-MS spectrum in figure 3 could help contextualize the complexity of the data, beyond the quality control purposes expressed in the figure. This would also help to visualize the described “polygon filter” - again, not an expressed priority of the paper, but helpful for readers to connect the software to data. Additionally, in figure 4, showing a comparison of the selected peptides between the 6 sample conditions could help to visualize the utility of the software for determining sample optimization. There’s also a slight disconnect in the captions for figure 4 - “cell 24” could refer to In [24] or Out[24]. This is worth clarifying with traditional a, b, c, d, e, f labels.
? The forward looking statement in the conclusion may provide a great opportunity to expand on future possible applications. For instance, do the authors see this being developed with additional data processing/analysis functionalities, or integrated into new/existing data analysis programs? Is there possible functionality to visualize and compare multiple datasets at once?

Review of “Boosting Toll-like receptor 4 signaling enhances the therapeutic outcome of antibiotic therapy in pneumococcal pneumonia” Casilge et al.
University of Alabama at Birmingham<br /> Bacterial Pathogenesis and Physiology Journal Club
Summary<br /> This manuscript is well written. The authors showing that in TLR4 agonist MPLA can be improved Streptococcus pneumoniae (Spn) clearance with a combination treatment of sub-inhibitory doses of amoxicillin in a mice model. Moreover, the authors found that MPLA enhances host immune response for invasive Spn via inducing the pro-inflammatory cytokines and up-regulating the granulocyte related genes. This paper is very reasonably demonstrated, but we have a few comments and clarifications.
Major Comments<br /> • The authors analyzed Spn titer on lung and spleen and analyzed gene expression or protein expression by RT-PCR or ELISA assay in lung or blood, respectably. Why you didn’t check Spn titer on blood and gene expression on spleen?
• The authors used 30ug AMX for “high-dose AMX monotherapy”. However, some of the other experiments 350 ug used. If the authors have a reason, please explain in the manuscript. It will be helpful to understand.
• The authors used one antibiotic “AMX”. How are other antibiotics? The title of this manuscript is “antibiotic therapy”. If you can, please check other antibiotics also. It will give a more powerful story.
• How is the AMX-resistant Spn (?-lactam resistant strains) strains and other pathogens? It clearly lowers the effective MIC of AMX in these experiments, but we wonder whether that extends to the possibility of overcoming at least moderate levels of AMR. These experiments are probably beyond the scope of this paper, but I would be interested to hear the authors’ opinion on whether this might be the case.

Congratulations on a nice work on delineating the transcriptional architecture of enhancers.
But, terms like "promoter", "core promoter" and "TSS" in our collective understanding have been etched in our minds to reflect gene-proximal elements necessary for gene transcription. Our knowledge of widespread intergenic transcription is only a decade old, and we are getting to learn deeper about how these transcriptional units function, and this paper is a great contribution towards that. Now, calling the similar elements within gene-distal enhancers by the very same name creates confusion. I believe there is a strong need to distinguish enhancer-embedded promoter elements from the classical meaning of such terms that normally refer to such elements at the 5' end of genes.
I suggest the authors, instead, use "ePromoter", "core ePromoter" and "eTSS" to reflect such elements that are embedded within enhancers and that primarily initiate enhancer transcription - a prefix "e" signifying the elements' location at/within enhancers.

The difference between Figures 4 and 5 is striking. In Figure 4, UniRep/BO is clearly superior to the other versions, whereas in Figure 5, even a random sequence performs well until higher iterations and there is never a clear difference between UniRep/BO and the other methods. You highlight that this task is very specific and is convex as explanations for why UniRep/BO is not clearly better, but I am still wondering why the performance for any method is not much better than random. Also, you also state that the sequence length is fixed at thirteen residues. In part A of the results, you mention that an advantage of BO is that the sequence length can change during optimization. Have you experimented with letting BO run with a variable length sequence on the unknown target matching problem? In addition, can you perform the AlphaFold task using the two ablated methods? I think including the ablation results for all three tasks would be helpful.
I think Figure 1 could be made clearer if the sequences and labels proposed from the logits went directly to the train step, instead of being directed first to a separate shape. This would make Figure 1 have a more triangular structure, with the logits at the top, the UniRep vector in the bottom left, and the prediction plot in the bottom right. I think this could help make the flow of information clearer.

I really appreciated this paper and I think it did a nice job in showing the accuracy and precision of the TIFF method. At the same time, I think a couple of edits could be made to help the clarity.
For example, figure 2(c) includes the proteins that had more than two valid values. These proteins, shown blue and red in figure 2(b), are shown red in figure 2(c). Therefore, changing the color scheme may be helpful to prevent misunderstanding.
Also, I really like the Venn Diagram, while can be a little confusing when considering what the “98%” in the overlapped part means.
Besides, figure 3(b) includes some data from previous research. And I noticed the standard method used in that paper is LC-MS. Since the one for the other figure is MS-MS, I think it will be nice to label LC-MS directly in figure 3(b).
In the end, personally, I hope there can be a distinct color scheme for figure 3(d), which shows the different pair-wise coefficients in different colors so that the comparison can be easier.

The experiments at different Skp concentrations (Fig. 2) are particularly interesting as you have chosen to work at near physiological concentrations. In our recent Skp publications, we have shown that in this concentrations range Skp populates an equilibrium between an inactive disordered monomeric state and the canonical active folded trimeric state (PMID: 33087350). This equilibrium being shifted toward Skp3 in presence of OmpX/tOmpA.
Would integrating the fact that Skp exist as a mix of inactive/active species explain why only ~80% of uOmpX molecules were in a Skp3–uOmpX complexed state even at the highest concentration of Skp (2.5 uM)?

This work describes the implementation of a data processing pipeline for acquiring high-resolution maps of microtubules (MTs) from cryo-electron microscopy (cryoEM) data using the RELION software. As in other pipelines for processing microtubule EM data, this implementation requires extensive custom processing because of the pseudosymmetric nature of most MTs assembled in vitro (also observed in vivo): a "seam" down the length of the assembly disrupts the otherwise helical symmetry. The broken symmetry means that existing methods for processing purely helical particles equate nonequivalent positions and produce low-quality reconstructions. The authors implement a treatment of these particles that accounts for the seam and produces high-resolution structures of the MT ? and ? asymmetric units. It builds on implementations of similar pipelines for the same purpose using other software, with the key advantage of conducting all steps in a single program that most cryoEM users are already familiar with. The pipeline consists of a set of scripts and a series of steps the user should complete in the RELION graphical user interface (gui) in order to obtain the asymmetric unit reconstructions. The authors test their pipeline on three example datasets with different decorators on the ? or ? subunits that aid in initial alignment and discrimination between the two, and note that they have successfully (with minor modifications) applied the pipeline to a more challenging dataset with both subunits decorated.
The major success of this paper is the clear and thorough description of the steps necessary to produce high-resolution ? and ? subunit reconstructions, complete with clear justification for each step and descriptions of expected results so that an advanced user can intervene when intermediate results deviate from expectations. This tool meets an immediate need in the structural biology community for analysis of MTs, which are inadequately reconstructed from cryoEM data by existing helical or strictly single-particle methods, and which play an important role in the cell interacting with a variety of other molecular machines. Ideally, it would be benchmarked against the other pipelines mentioned in the paper (e.g. https://github.com/nogalesl... from: https://www.ncbi.nlm.nih.go... "https://www.ncbi.nlm.nih.gov/pubmed/26424086)") but as one of us (JSF) knows from personal experience that it can be tricky to set up the necessary EMAN and frealign environments correctly to do such benchmarking properly. Here, the ability to complete this analysis without exporting steps to other programs could be a major boost in accessibility. Moreover, as the authors have built upon a popular cryoEM image processing program that has a gui highly accessible to novice and intermediate users as well as command-line tools that expert users may use for more advanced customizations and interventions, we anticipate this pipeline will be enthusiastically adopted by many users.
We also applaud the authors' choice to make the scripts open-source and publicly available on github, which will facilitate the active conversation between users and developers (and sometimes software developers who did not author the original work) that lead to major breakthroughs and advancements in later versions. However, we cannot comment on the scripts themselves yet as a full path to the source code is not provided in the manuscript and a search for “MiRP relion github” didn’t yield anything informative. We would like to request the authors include it in the revised manuscript and also provide it to us during the review process so we may evaluate this important component of the work. We recommend using Zenodo (https://zenodo.org/) "https://zenodo.org/)") to generate a DOI for a snapshot of the repository, which will also produce a timestamp and facilitate formal versioning.
We identify a few major weaknesses in the manuscript in its current form, all of which we hope the authors can address in a revision. First, the final, high-resolution reconstruction is the ?? dimer, not the C1 reconstruction of a full helical turn, which may not serve the goals of all users. The authors identify the final averaging step that disrupts the density for all but the ?? dimer directly opposite the seam and describe alternative approaches, including one implemented by the Carter group while the manuscript was in preparation. We would strongly encourage them to implement one of these approaches so that biological questions that require examination of the whole MT can also be addressed. We are also unclear on how the present implementation would preocess both the microtubule and fiducial protein for datasets with dynein or EB3 bound, and would like to see this explicitly discussed (or better, tested if EMPIAR datasets are available).
Second, at times the authors describe what they expect from data they have not processed, for example on page 14 lines 1-4. Given that they have the necessary tools in-hand and this work describes the method, we would press them to test this type of claim and describe the supporting evidence. They have also described processing a dataset with fiducial markers on both ? and ? monomers but not described the modifications they had to make to the pipeline for this dataset, and they have not yet (to our knowledge) used the method to process undecorated MTs. As they cite successful processing of undecorated MTs by the Nogales group, proof-of-concept processing of undecorated MTs would be an important component of making this pipeline at least as useful as existing methods. The other case where we would strongly prefer to see the authors test their claims is on page 12 lines 46-48, where they speculate on the effects of excluding some MTs from further analysis, and although the authors do not make any claims about performance using automated MT picking, we would be very interested to see this tested (even if the result is that it is discouraged).
Third, while we agree with the statement: “strikingly, although application of MiRP compared to standard helical processing has a negligible effect on the reported reconstruction resolution by FSC (Fig. 6c), the structural details are clearly superior in quality,” based on the snapshots of density shown at a specific contour in Fig 6 and Supp Fig 3, it is possible to use tubulin model refinement and other quantitative evaluations of the map to validate this statement. For example, compared to the standard helical map we would expect a higher quality reconstruction to have a smaller convergence rmsd when multiple independent models are rebuilt into the map (as in: https://www.ncbi.nlm.nih.go...; "https://www.ncbi.nlm.nih.gov/pubmed/30449687);") a better EMRinger score (https://www.ncbi.nlm.nih.go... "https://www.ncbi.nlm.nih.gov/pubmed/26280328)") when evaluated with the same starting model rigid body fitted into the map; and lower B-factors/better model geometry when an atomic model is refined.
Fourth, reiterating that this is a methods paper, we find it critical that the raw data be made available on EMDB for all datasets described in the manuscript, not just the C1 reconstructions and symmetrized asymmetric units. This is important for reproducibility, open science, and the development of exciting new methods like this one using publicly available test data.
In sum, we find this an important piece of work that will immediately improve the ability of groups working on MTs to recover high-resolution structures, pending our several major reservations that we hope the authors will resolve in a revision. We also identify several minor points that could be improved, mostly regarding readability, and a few suggestions for alternative implementations of some steps in this or a future version of the pipeline. As the line numbers do not appear to be spaced the same as the text, for these points, we have indicated the closest line number to the line when printed.
Some figures or tables referenced in the main text are not referenced correctly, such as on page 9 line 31, Fig. 6aii (referencing a panel that does not exist).
Table 1 should include accession codes in the EMDB.
The authors might comment on the biological relevance of MTs with seams, given that these are more often encountered in vitro and much less often in vivo, preferably in the introduction.
We suggest a figure that visually highlights the symptoms of misalignment of the seam and/or helical averaging of MTs with seams. Including correlation coefficients with this figure could help illustrate the challenge this pipeline overcomes. This could also illustrate the signal boost of the superaverage and the symptoms of out-of-register units. The figure could be referenced at several points later in the text to explain why certain steps are necessary.
At the end of the first paragraph on page 6, the authors describe "structural constraints of MT polymers" but apply restraints in orientational and translational searches. It would be helpful to expand on the rigidity of these restraints and whether it varies with distance to further neighbors, if applicable. Ideally (or possibly in a future version), the authors could consider restraining each ? or ? monomer relative to its immediate neighbors and using this approach in combination with variable restraint rigidity to aid in reconstructions of monomers at the seam and in distorted regions.
Several points regarding resolution starting at the end of page 6 and continuing in the first paragraph on page 7 describe increments of resolution or changing pixel size by binning, which have no meaning in isolation (e.g. a difference of 0.2 Å or binning x 4). The starting or ending absolute quantities should be included (e.g. improvement of the resolution to 3.2 Å or a final pixel size of 3 Å). This is repeated on page 11 lines 11-12.
The authors describe that "there is a clear bias towards a certain range of Rot angles" on page 8 line 16, but as this is the expected behavior and not a ground truth, it should be described as such.
Similarly, on page 9 line 19, the authors intermix behavior on their test data ("As expected") with description of the method, and should more clearly separate these.
On page 8 lines 18-22, the authors describe their approach for using the bias toward one Rot angle to select the correct seam location. We recommend testing the alternative method of a grid search over correlation coefficients, or describing how this is effectively accomplished during the global search step.
On page 8 lines 21-22, the result of the Rot search is described as an approximation. It would be helpful to clarify whether this result is precise but sometimes inaccurate, or accurate but known to be imprecise.
On page 8 in the section on X-Y shift smoothing, the authors describe a remedy for out-of-register asymmetric units involving resetting excessively large shifts to zero and re-refining. We propose an alternative method by analysis of the distribution of X-Y shifts that identifies the out-of-register shift vector and adjusts excessively large shifts by modulo arithmetic. This would reduce the error in the reset shifts.
As part of the same description on page 8 lines 47-48, the authors describe enforcing all X/Y shifts in a MT to follow a single slope and intercept, and should clarify whether this is constrained or restrained.
The authors could expand on the process of 'segment average' image generation on page 4 line 29 and the source of known helical parameters on page 4 line 33.
The sample preparation for cryoEM section starting on page 3 could include greater detail, e.g. Vitrobot parameters during blotting and freezing.
The authors could clarify the difference between defects and switches in PF number on page 7, lines 27-28.
The description of a 'clean' seam on page 10 line 48 is confusing. Describing this as a MT with no seam might be clearer, if that is the correct interpretation.
There are a couple creative uses of the word "allocation" — on page 9 line 6 we suggest substituting with "positioning" and on page 13 line 22 we suggest substituting with "assignment".
The wording on page 5 line 52 seems to imply the RELION nomenclature preceded the Euler angle nomenclature used in many other applications, so we recommend dropping the modifier "former".
The wording on page 7 line 5 implies the previously implemented approaches are lacking in some way, and we recommend dropping the modifier "albeit". This is repeated on page 12 line 42.
The authors could describe which of the operations through the gui could alternatively be run on the command line on page 5, lines 59-60.
On page 13 line 21, the authors claim their implementation is "the only way to avoid introducing artefacts." This may be an overly bold claim.
We are unsure what the authors mean to do with the "41 Å shifted positions" on page 9 line 7.
Some of the word choices could be made more accessible to all readers, for example by using the more common and equivalent "while" instead of "whilst" in several instances.
The sentence "Initial Tilt ... picking coordinates" on page 6 lines 54-56 is unwieldy and could be rephrased.
We find the sentence beginning "In other words" on page 8 lines 2-4 redundant and unnecessary.
The qualifier "data collection parameters" should not accompany ice thickness on page 9 line 42.
We would prefer sticking to one set of units on page 10 line 1 and substituting "sub-10 Å" for "subnanometer".
The abbreviation "(DQE)" on page 9 line 43 is not used again and may be omitted.
There are several spacing errors throughout the text. Between a numeral and a unit, there should be no space, except where the next character is º or %.
On page 8 line 4 and in several other instances, where "however" is an interjection, it should also be preceded by a comma, e.g. "this register is, however, very error prone".
There is a typo on page 3 line 52 (1 mg/ml --> 1 mg/mL), an incorrect abbreviation on page 4 line 6 (sec --> s), an overly dense abbreviation on page 4 line 59 (4xbin), a typo on page 4 line 53 (smoothened --> smoothed), a typo on page 5 line 14 (psi/tilt/ranges --> Psi/Tilt ranges), use of redundant "around" and "~" modifiers on the same quantities on page 6 line 53, incorrect pluralisation on page 7 lines 33-34 (confidence --> confidences), an unnecessary word "score" on page 8 line 7, a missing word "good" in "good signal to noise and good angular distribution" on page 9 line 33, an unnecessary hyphen in "ice-thickness" on page 9 line 42, and an unnecessary comma in "reconstructions, remains" on page 9 line 56.

This paper by Wen, Luca, and Pique-Regi presents a novel statistical approach to eQTL mapping. This work builds upon a series of recent methods for association mapping in a Bayesian framework, by applying a meta analysis to a trans population eQTL cohort, modeling the effects of allelic heterogeneity under causal variant uncertainty, and incorporating regulatory element annotation data as an informative prior. This method also improves the interpretability of loci that appear to have subgroup specific effects that are actually caused by multiple, independent, linked causal variants. In general, this is an important topic that will be of broad interest, the paper is generally well written, and the author’s conclusions follow logically from the stated analyses.
I have the following concerns:
the meta analysis identifies more associations than the union of the single group analyses, I don’t think this is a particularly meaningful comparison. Given the difference in samples sizes, it seems obvious that the multi group analysis would have much greater power than the single group analyses. The authors need a better way to make this point.
PIP clusters. At several points in the manuscript (e.g., Figure 3), the authors discuss SNP sets that fall into ‘clusters’ based on their pattern of inclusion in the model sampling. These clusters of SNPs appear to represent groups of SNPs in high LD that cannot be differentiated statistically. Because of the fact that, within each of these clusters, there is likely one causal variant, the delineation of the clusters is extremely important. If I understand correctly, these clusters cannot by identified from the PIPs alone, but rather must be extracted from the sampling results (e.g., a collection of 8 SNPs in perfect LD could have a summed PIP of ~1, but each individual SNP would only have a PIP of ~0.12). It is not clear from the text if these clusters of SNPs are annotated automatically or if this requires manual intervention. Users of the software would certainly benefit if this annotation was automated.
Characteristics of PIP clusters. I’d be curious to know about the relative distance to the TSS of SNPs that from multiple clusters. In other words, if a gene has two independent clusters of SNPs with high summed PIPs, I’d be interested to know if the cluster with the greater PIP is more often closer to the TSS than the second cluster.
Resolution. The authors demonstrate very clearly that the use of multi population cohorts for eQTL fine mapping improves resolution by ~50%. This is a subject of great interest to the disease mapping community. I think the authors have a very interesting collection of analyses and data that they could explore a bit more deeply. Perhaps these data warrant a display item as opposed to just the limited treatment in the text?
Model incorporating TFBSs. How were SNPs classified into not overlapping DHSs, footprint SNPs, and binding variants? More detail or a reference is needed. What is the relative importance TFBS overlap vs. distance to the TSS? Is it possible for the authors to quantify the fraction of the PIP that is overlaps footprint or binding variants? Or conversely, can the authors estimate what fraction of eQTLs do not appear to overlap a TFBS?
Fig 6. The authors state that the multi SNP model yields an even greater enrichment of eSNPs about the TSS. However, this conclusion is neither directly quantified nor visualized. For example, figure 6 could be changed to present the results from both the multi SNP analysis and the single SNP analysis, which might make this very interesting result much more intuitive. I also wonder if this increased resolution could be used to ask if the distribution SNP enrichment is symmetrical about the TSS?
Direction of effects at multiple-eQTL loci. The example presented in figure 3 depicts a gene with multiple independent eQTL effects. At this particular locus, the minor allele at the largest effect SNP cluster is associated with an increase in expression while the minor allele at the 2nd, 3rd, and 4th clusters is associated with a decrease. I’d be interested to know how often the data fit this pattern, as opposed to the situation where the independent effects have concordant effect directions.
‘Functional analysis of eQTLs’. While I understand that it is common practice to refer to SNP enrichment analyses as ‘functional’ analyses, it does not seem appropriate to me. Simply calling it ‘Enrichment analysis of eQTLs’ would be more accurate.

Unfortunately, this prior body of work is not very well acknowledged or discussed in the paper. For instance, Bakker et al have reported a link between Tet resistance and Tet resistance in human and animal isolates (DOI: 10.1128/JCM.01171-10). Recently, Knetsch et al. have shown the presence of tet40 in RT078 already (unlike the claim in the abstract) - doi:10.1128/JCM.01384-17. I also find it surprising that though fluoroquinolone resistance is mentioned as a driver of epidemicity, the recent Nature paper from the Britton group (which also deals with RT078) is not discussed - DOI: 10.1038/nature25178. I hope the authors will provide a more balanced view in an updated version of this manuscript.

Review by University of Alabama at Birmingham Bacterial Pathogenesis & Physiology Summer Journal Club:
This paper begins to elucidate the role of GumB, an IgaA ortholog in a S. marcescens rabbit<br /> keratitis model. Overall, we feel this paper is well written and begins to demonstrate the role of GumB on the Rcs system in S. marcescens. We found all experiments to be insightful and straightforward. We especially appreciate the complementation experiments that were performed as we feel these types of experiments are lacking in many animal infection models.
Below are our critiques:<br /> 1. Introducing the roles of wecA and wza in context with the Rcs system sooner in the introduction of the paper would allow us to understand why these mutants were used in early experiments in the manuscript.
More introduction for shlBA would also be useful.
The experiments presented in this manuscript utilize double mutants without single mutant controls. Including these experiments would improve the clarity of the manuscript.
Including a cartoon of the Rcs system and its associated roles along with its regulation by GumB would allow for the reader to understand the system much quicker and easier than what is currently presented.
Throughout the manuscript, many between comparisons are made in the figures that we feel may be unnecessary when there are controls present. Performing more comparisons of mutants to controls may be more informative

You include a lot, so you don't necessarily have to add something about the minimum amount of reads needed for an application like self-identification. However, at least within the window where you are able to do so, I think some readers may be interested in seeing a comparison to Gencove.

Nice paper and very nice idea. I like figure 1, but suggest a couple of things - firstly can you be clear on the bases of the logarithm, secondly could you show the slope explicitly. I have a more fundamental issue with interpretation - extrapolating this fit would see the men and women lines cross: you know this doesn't happen. So beyond age 50, it looks like ageing behaves differently than before age 50. As you recognise mortality causes are different between men and women, but also by age. In particular many younger men die due to risky behaviour, which diminishes as they age (or grow up!) To what extent can your findings be explained as reverse ageing in men due to this effect, rather than differences in the acceleration of morbidity between men and women?

The study addresses an important problem. A unified dataset of gene-trait associations based on GWAS would be valuable resource.

Furthermore, the methods for association integration appear suboptimal, although more discussion of the reasons behind the design decisions might sway my opinion.

I left a comment on the Nature commentary on this paper. Probably it should have been left here, so I'll repeat it.
Congratulations to Curry et al for managing to have an impact on what I now like to call the legacy publishing industry. It's taken far too long. It was 1997 when Seglen et al pointed out that the number of citations that an article gets is not detectably correlated with the impact factor of the journal in which it appears. I emphasized it again in 2003, in this journal [Nature].
After 20 years of pressure, it seems that something may, at last, be done about it. Not enough, of course. The impact factor has had such a corrupting effect on science that it should be forgotten altogether. Perhaps, when citation distributions are published, it will become so obvious that its mean is such an absurd measure that will happen. Expect that to take another 20 years.
The really interesting question, though, is whether Nature or Science will still be publishing original research 20 years hence. By then I expect they will be reduced to news journals, and research will be published in far cheaper journals, with fully open access. Even if that doesn't happen for good scientific reasons, it may well happen because universities can no longer afford the huge cost of Elsevier, Cell Press and NPG journals.

I spent about 90 minutes reading this preprint and am providing my thoughts on it in case they might be of use to the authors or anyone else. I am not an expert in this field but am very interested in the topic. Overall I enjoyed reading the paper and feel like I learned a lot from it.
My summary of the paper (to see if I “got it”): the authors raise the question of how PIP2 is involved in so many cellular processes and propose testing the hypothesis that PIP2 is organized into separate spatial domains that carry out different functions. The authors note the correlation that PIP2 is enriched at different functional sites but also that it is not clear whether PIP2 is upstream or downstream from any particular function. I began to get confused at around line 64 (version 1 of the paper) where the authors make some distinction about lipid rafts vs other types of structures that PIP2 might regulate (for example, on line 65 where they say “could this regulate”, I was unsure of what “this” referred to). Ultimately, I understand the question of the paper to be about whether or not PIP2 movement in the plasma membrane is slowed when it is in functional membrane domains as one might expect it to be. They note that PIP2 has been found to move rapidly but based on measurements of bulk PIP2 movement. They also note that, in extracellular lipids, the cytoskeleton has been shown to slow diffusion and this is a key justification of their hypothesis but without looking up the referenced papers I am very unsure about what this means. Finally they describe their approach to the problem - the use of sptPALM to monitor single particles - and briefly describe their results.
The authors begin the description of their results by noting that they are monitoring “free” PIP2 that is bound to sensor molecules, since binding to the sensor prevents binding to effector proteins - an important point that is nicely reinforced by Figure 1. The authors note that biosensor-bound PIP2 has the same diffusion coefficient as free PIP2 which is very surprising. The authors spend some time establishing the rigor of their technique which I found, as someone who knows very little about it, to be convincing and comforting. A key assay is whether or not the diffusion is Brownian in nature, or if it is not (i.e. affected by something). I got a little lost in the description of the results in the paragraph starting at line 140 thinking that the conclusion is that the dynamics are mostly Brownian but there are some differences. At line 183 the authors note a deficiency in the mean diffusion coefficient– that it will not detect trajectories with different classes. I’m intrigued but a little confused - in other words, different collections of trajectories could yield the same “D” - interesting! The author’s solution is to calculate D for different classes of trajectories. Overall the main result so far is that PIP2-biosensory movement is mostly unhindered, but a small amount is potentially hindered.
The next section is about how specific cellular membrane structures influence PIP2-biosensor movement. The first result is the PIP2-biosensor complex is not hindered at ER-PM contact sites. The authors introduce a control involving chemically induced dimerization of the biosensor but I was somewhat confused as to what this experiment as actually controlling for. They show that they can detect hindered movement but my confusion may arise because that wasn’t something that I considered to be an issue. Ultimately they find that PIP2-biosensor dynamics seem to be the same in most cortical structures but not in spectrin and septin containing structures- a very interesting result!
Conclusion: I found this to be a very interesting study with many interesting results. I was somewhat confused by the presentation. For example, the abstract states, “how a single class of lipid molecules independently regulate so many parallel processes remains an open question” but I’m not sure that this question is being addressed in the paper. My takeaway is that the paper asks if the dynamics of free PIP2 (PIP2-biosensor complexes) is the same in different cortical structures as it is outside of them. The answer seems to be that for the most part it is and that the data and arguments presented in the paper make a convincing case for this. Making the paper more clear about what it is really about (if my takeaway is correct), and also discussing what factors might influence whether or not free PIP2 would move through cortical structures freely, could be helpful improvements to readers.

Dear authors - interesting work!
What about overfitting/data dredging in your work? "The reported result of assessment is based on the average f-measure for the 10-folds for testing dataset."
When you go from genes to isoforms you also increase the number of predictor variables which make overfitting more possible (not necessarily more likely though).
I couldn't see the variance of these f-measures from CV which is normally a signature of overfitting (if the variance is very high).
For a full analysis I would suggest you split your datasets into training (MCC or F estimated by CV on this set) and validation set (MCC or F estimated by fitting final model to full training set - evaluate on this set). This is very close to what is done in kaggle competitions etc. where you actually measure your performance yourself (internal performance) but also need to predict on new data (external performance). If these two measures are very different the chosen model is not good.
Check "Comparison of RNA-seq and microarray-based models for clinical endpoint prediction". The problem is that when using CV to compare and select best models you may end up with the model that accidentally fits (using CV) your dataset best (data dredging). So basically you would like to see a nice correlation between training performance (internal performance) and validation performance (external performance) - and only use internal performance to rank models/parameters.

It seems the URL to your tool is only available at the very end of the manuscript, although it would be convenient to have it earlier, preferably at the end of the abstract.

It seems your code is not compatible with python 3, which is a problem. Python2.7 is not going to be supported for that long anymore, and by publishing tools with an outdated python interpreter now you are not writing future-proof software.

Review of Gaddy et al. (2017) from a Computational Biological perspective<br /> by the students in Computational Biology Course (MICR607), University of Tennessee. <br /> Feb 08, 2018
The paper investigates the vascular endothelial growth factor (VEGF) that could be targeted for inhibiting the angiogenesis by tumors in mice. The authors model the rate of change of tumor volume (V) over time (t) in response to the volume (V) itself and the VEGF concentration (as a function of “angiogenic signal”: Ang(t) ) as an ordinary differential equation (ODE)). It is suggested that the growth of tumors explicitly depends on the Ang, which is the signal produced when VEGF binds to its receptor on tumor andothelial cells. Their model is applied to investigate how tumor growth-kinetics is influenced by the anti-angiogenetic treatment targeting VEGF, i.e., anti-VEGF treatment, computing Ang(t) as a control variable in the ODE model that drives V(t). <br /> The authors conclude that the parameters that characterize the growth of the tumors could be “well-predicted” in response to the anti-VEGF therapy -whereas the effect differs depending on the type of the tumor- and compliment pre-clinical in vivo mouse studies. Authors further claim that the model was “validated” by being able to predict the growth of the tumors with in vivo measurements of xenograft tumor volume in response to the data of anti-angiogenetic treatment.<br /> Here, we intend to give a feedback on the aspect of the modeling (i.e., computational biological perspective) and the scientific methods used in the study. <br /> In summary, the model (1) that the authors used seems inadequate to capture the underlying dynamics of the processes, because it seems that the estimated error distributions over time are biased (i.e., indicating patterns - although the actual distributions of residuals were not shown), and thus we believe that the model has room for improvement in terms of its mathematical formulation (capturing the apparent sigmoid shape in tumor growth dynamics). It seems that a major factor(s) is(are) missing in the formulation, although the authors claim that the model “accurately predicts” and “is highly successful” in capturing the growth dynamics and “matches the tumor growth data”. Mechanics governing the mathematical model construction (functional responses) need to be explicitly given in more details. Besides, authors should also consider comparing alternative models that capture additional/alternative mechanics (as some listed under the discussion) to get a better understanding of the processes in a weighted-information perspective (i.e., using information criteria). Furthermore, the statistical analyses that could handle Mixed Effect error structures, combining the 6 independent data sets, are required for generalizing the mechanics and the treatment effects across experiments, to see the robustness of conclusions. <br /> Major comments:<br /> 1. The authors use two models (1 & 2), model 2 with an additional parameter CAng, so that they become nested models. The authors claim that “CAng does not significantly influence the quality of fit to the experimental data” and “does not improve the fit, because the estimated value of the coefficient is highly variable.” Furthermore, they say “CAng parameter is non-identifiable”. <br /> The reason why this occurs is that in the model, (k0CAng/Ang0) is a single parameter in mathematical sense. Thus, (k0CAng/Ang0) will remain the same in the estimates, while the estimates of CAng and Ang0 can take any values, keeping the CAng/Ang0 ratio the same. Thus, adding CAng to model 1 makes no statistical change, thus, any improvement to the understanding. Note that CAng=1 in model 1, but the true value of which, if present, can be naturally statistically absorbed into Ang0 estimate. Thus, model 2 is statistically redundant as parameters cannot be statistically distinguishable. We suggest that authors should remove model 2 from the paper entirely. Model 2 cannot be considered as an alternative model.
Furthermore, model 1 can be mathematically reduced to only 3 parameters from the given 4 parameters: k0/Ang0 , k0/k1 , and ????. This will make the analyses and interpretations simpler.
The model 1 seems to be lacking proper mechanics being incorporated. We observe that estimation errors in fitting model 1 to data (Fig.1) are systematically biased (i.e., they form patterns). The model 1 seems to be under-fitting, and the tumor growth is apparently sigmoid in shape with increasing time, which authors also acknowledge at the discussion. Yet, the authors discuss very little about as to why tumor growth changes from exponential to logistic, and do not make an effort to model it, yet they simply propose a model that has only exponential and linear features. One possibility for such mechanics (i.e., the functional relations that the data indicate) could be that at larger sizes, tumors are better recognized by immune responses, and this may reduce tumor growth patterns. Alternatively, larger tumors may have fewer cells dividing (e.g., core could contain dead cells) leading to an apparent slowing down of the growth rate, deviated from being exponential. Can the data be used to discriminate between these alternative mechanics through alternative models? In essence, given the biases in how the models described the data (i.e., systematic deviations of model predictions from the data), it seems that alternative models need to be considered. Would a model with logistic growth be more accurate description of the data?
Apparently, the figures also indicate that there may be a time-lag in response to treatments, which is varying between 2-3 weeks across the 6 data sets. Besides, the model ignores the point at which the treatment started. Lacking such, the mean curve gets warped at an arbitrary time, as the model is not a stochastic formulation, but deterministic. Authors may consider modeling this time-lag explicitly, and/or incorporate the starting points of treatments using a spline-fit of two models separated by time, assuming the latter model has a response curve sigmoid in shape (rather than linear or exponential) as the data indicate, with mechanistic justifications.
It appears from visual inspection that the error structure of the statistical model is inadequate to generalize the results, or the effect of the treatments, for e.g., Fig. 3 & 5. Will using Mixed Effect Modeling approach to fit model to data solve this issue?
The paper has no description of what Ang(t) is thus precluding our ability to reproduce results of the paper. This function must be defined.
In predicting the response to anti-VEGF treatment, authors may analyse RTV=Vtreatment/Vcontrol as a function of time (t), rather than a ratio by the end of the simulation as it was done in the paper. Such will give a better understanding of the treatment process, length of time, and their effectiveness. Mixed Effect modeling approach will also enable to handle errors in the prediction of RTV in a more meaningful way giving a generalized perspective.
The method of solving ODE’s needs to be explicitly stated (e.g., numerical), and what software was used to solve them, rather than simply stating “System Biology Toolbox” in Matlab, again, to improve chances of this work being reproduced by other investigators.
We suggest that the authors change the subjective language such as “excellent job of matching”, “accurately predict”, and “successfully predict” to objective scientific terminology supported by statistical justification. Also, the use of word “validation” implies too strongly that the model is correct. Reading a paper by Oreskes et al. Science (1994) could be useful in this regard.
We would discourage authors to use the term “compartmental model” as the given model is independent of the other macro-model described in the paper given with reference to a series of other papers. Reader may get confused by such terminology. The fundamentals of the model formulation (functional relationships) need to be more descriptively stated here, rather than directing the reader to read multiple other published papers and to mine their own for the baseline mathematical model. Conceptual diagram is insufficient.
It is unclear why model-fitting was done 20 times to estimate the parameters. If model complexity matches data complexity, convergence should be unique, with no need of multiple “fittings”.
Because Ang(t) is a free parameter, it is unclear how the model is used to fully predict growth of the tumor with treatment. Was Ang(t) “chosen” to fit the treatment data? If yes, then it is a poor way to confirm a model.
The observation that only 3-5 data points -which seem to fall on the fitted line - are sufficient to estimate several model parameters seems strange, and may be due to well-chosen initial guesses for model parameters. From experience, it is likely that multiple sets of parameters can predict early growth but fail in long-term growth. The way authors did those fitting needs to be described.
Minor comments:<br /> 1. (Pg.6) Model construction: The details of the fundamentals of the formulation of the model in this paper are given by another paper cited by a paper cited by this paper (28). Also, 6 references are given respect to the model. Should the reader read all those papers to understand the given model fully? The model in paper (27) has 40 ODEs and 94 chemical reactions. The reader may find it very difficult to understand the connectivity of those models to the model-extension suggested by this paper by merely referring to those papers. The fundamental models are needed to be presented here explicitly, and then the extension proposed needs to be stated. <br /> 2. (P.g. 18): First paragraph of the discussion is more appropriate as an introduction to the modeling section. <br /> 3. (Pg. 7) Model fitting: A description of the data that the authors used to fit to and parameterize the models, regardless of whether they are published or otherwise, and their respective experimental methods, need to be stated here (at least briefly) for a better understanding and evaluation of the methods. <br /> 4. (Pg. 14 & Fig. 6): “PLSR” is being used without describing it. What is it? <br /> 5. (Fig. 6): The meaning of “component 1 & 2” should be described briefly.<br /> 6. (Fig. 4): The point regarding efficacy of bevacizumab is overstated given that the drug has been withdrawn from the market.<br /> 7. Statement that mouse models are a useful platform for biomarker discovery for diseases of humans needs proper citations.<br /> 8. Eqn 1a and 1b are not needed rather a simplification can be done in one step.<br /> 9. It seems like the paper needs a lot of explanation on various unexplained sections and assumptions, as pointed out by other reviewers under minor comments, to make it easier for the reader to follow the paper.

Interesting study with a challenging protein. Nice to read about the conformational dynamics of this GPCR.
A few constructive suggestions:
The introduction states that the structure of the NTS1-Gq complex is available (..."ternary complexes with both the heterotrimeric Gq protein..."). However, it is Gi, not Gq. Figure 3E should also be corrected.
Have you considered discussing your findings in the context of these two other publications?<br /> "Probing the conformational states of neurotensin receptor 1 variants by NMR site-directed methyl labeling" (https://doi.org/10.1002/cbi... "https://doi.org/10.1002/cbic.202000541)") and "Activation dynamics of the neurotensin G protein-coupled receptor 1" (https://doi.org/10.1021/acs... "https://doi.org/10.1021/acs.jctc.8b00216)").
You could explain that SR142948 has inverse agonist properties. According to the definition, a true neutral antagonist would be expected to have no impact on the receptor conformational equilibrium.
The CWxP motif could also be mentioned among the conserved microswitches in the introduction.
In the introduction, it could be specified that the ~50% decrease in the volume of the orthosteric ligand-binding site upon agonist binding is compared to the volume of inverse agonist-binding sites. In addition, I believe that the term "extracellular vestibule" is not entirely correct here because the contraction of the ligand-binding site reaches relatively deep in the TM bundle. Orthosteric ligand-binding site or cavity or pocket is possibly the more suitable term.
In Figure 1A, the colors of the bars are different from what is written in the corresponding caption.
All the best,<br /> Mattia

As mentioned in the article, many of the existing methods for integrating transcriptomic data and genome-scale models of metabolism rely on user-specified thresholds of gene expression, which may induce unwanted bias.
It might be worth mentioning other methods that do not rely on user-specified thresholds of gene expression. The paper by Lee et al. would be a prime example.

This paper puts emphasis on the rates of action and that is laudable, given that many processes are not in a steady state in real life.
If you can estimate all of the microscopic rate constants for a realistic reaction mechanism then you can predict the rates of any macroscopic process from p(t) = p(0) exp (Qt) where p(t) is the vector of occupancies of each state at time t, and Q is the transition rate matrix. So far. that has been achieved only for a handful of ion channels, using single channel analysis. I fear that we are nowhere near to achieving it for GPCR, partly because the methods have insufficient resolution, and partly because there are no mechanisms sufficiently detailed and realistic to allow such predictions. For example, as far as I know, nobody has yet worked out how to allow properly for the concentration of G protein. This means, I think, that attempts to interpret the rates of events at GPCR in mechanistic terms are unlikely to cast much light on physical reality.
There are examples that illustrate these in Colquhoun & Lape (2012) (that was my last contribution to this field): available at http://www.onemol.org.uk/Co...

Dear authors,<br /> Thanks a lot for this nice article! The topic and the questions it raises are fascinating and definitely needed to be addressed. I have few comments about method details that were absent from the manuscript, and that you may consider adding:
-You refer to the original publication by Bubly et al for the breeding methods of the different selection regimes you used (which is fine), but in this publication we have no information on parameters that can influence the microbiota. For instance, you could give some details about the opportunities for microorganisms to jump from one generation to the next (only through egg chorion? Adults could defecate in the bottle for next generation? Etc.). You could also mention the food composition and if preservatives were used (they both strongly affect the microbiota)<br /> -I missed the details of the collection of your different flies. You only indicated you sampled 20 individuals in each population or each selection regime, but we do not know if those individuals were collected 1) after the stress in a “selection generation”, 2) during the “no selection” generation, or 3) after x generations bred in identical conditions. You mention “common garden” in the abstract and in the conclusion, but there is no mention of this in the methods… Also, additional parameters such as the age of the flies, time spent in the same bottle etc. do affect a lot the microbiota composition<br /> -By not eliminating parental effects (like transgenerational transmission of microbiota), one potential issue is to measure the filtering effect of the treatment directly on bacteria rather than on the fly-microtiota system (or holobiont). This is something important, weakening the "holobiont" aspects of your discussion, and that you should discuss in my opinion. A way to test that would have been to eliminate the microbiota of the flies, and let all lines grow with the same starting microbiota. In such case, still observing different communities would indeed indicate co-evolution at the holobiont scale. I understand these flies were collected a while ago, probably without this experiment in mind, but you have to acknowledge the limits of your experimental setup.
Hope you will find my suggestions relevant. I much enjoyed reading this paper and this is why I wanted to point out some potential issues.<br /> Best regards

The drugs they identified are not new mechanisms -- They are all mTOR inhibitors or PI3K inhibitors. This would be more interesting if it found a new MoA drug that slowed aging in cells, and then extended lifespan in some model organism(s).

The presence of T cells that recognize the viral antigens isn't surprising. The confirmation of such cells existing also does not prove functional immunity, where the cells are able to control infection- that is pure speculation, and no such data exists in this paper. There is no follow-up of such individuals to see if they are protected by virtue of these reactive cells, and for how long they would be protected. It is published that the virus downregulates class I expression. It is published that the virus enters T cells. It is published that the virus cleaves furin. All of these render the hope of long term T cell immunity Tenuous. Finally, T cell immunity requires one to be infected, while B cell immunity where there are circulating antibodies does not reinfection. If one does not have circulating antibodies and must rely on T cell immunity, reinfection or infection is guaranteed on a cellular basis. I anticipate serial challenges to immunity, and with possible epitope spread/ mutation, this gives me great concern.

As an alternative to HADDOCK, one can use distance restraints to guide ClusPro server to dock proteins (Kozakov D, Hall DR, Xia B, Porter KA, Padhorny D, Yueh C, Beglov D, Vajda S.

Although the use of low-quality starting structures is debatable, these often are enough to roughly define the interaction interface.
