Reviewer #1: The article is very clearly written. The authors lay out a timeline of the developments of the field that to me seems fairly complete and leads directly to the new method as a substantial increase in the field. The motivation for focusing on the structural identifiability is made fairly clear. The method is well-described and after reading it, it's clear that it should work. The evidence then demonstrates that it does work. I can easily see this method and this package being used by many researchers in practice. That said, there are some improvements that should probably be made to the paper before publication. For one, I think that section 3.4 is unnecessary. I think it's fairly clear that this kind of numerical method needs to be computed on some finite support so practically all determinations are going to be made in some box. I don't think that more than a sentence or a paragraph is really required to get that point across. Secondly, the paper itself doesn't seem to have a lot of the validation. One example is used as validation, but the paper needs more. When I look at the package they discuss, I can see 5 clear examples with Binder links that demonstrate the method on more systems: some of this should be in the paper instead of 3.4 in order to more broadly demonstrate the validity of this method. Next, what they established was "structural efficiency", i.e. efficiency in terms of likelihood function evaluations. But it would've been nice to also see "practical efficiency", i.e. raw timings for the MATLAB method and Julia and Python implementation of the new methods, and use this to demonstrate a clear orders of magnitude actual performance improvement. Overall I think it's a really good paper, a good idea, and a strong result with just some touch-ups requires to really hammer home the advance in a more clear way. Reviewer #2: This article presents a novel method to study practical identifiability of parameters of ODE-based models. The method is innovative and seems to overcome existing methods in terms of computational cost, at least in the presented example. It can definitely be useful for the Research community, especially since the authors have made it freely available either in Julia or in Python. The article is very clear and well written. It cites all relevant literature. I have three minor comments: -Equation 7 : precise the values for j, to make clearer the fact that this is a system of more than 2 equations. -Equation 8: it is not obvious how the authors transformed system (7) into system (8). More explanations are needed here since this is key to understand the algorithm. Are the systems strictly equivalent? In the definition of c, the authors need to precise the position of the “1” in the vector. -The authors claim in the Abstract and Introduction that their method provides more accurate estimation of confidence Interval bounds. However, this is not demonstrated in the article, neither theoretically, nor computationally (On the opposite, they do provide some evidence of the lower computational cost of their algorithm compared to existing ones). Please either add the corresponding evidence or modify the text. ********** Have all data underlying the figures and results presented in the manuscript been provided?

Revision 1 |
Dear Mr. Borisov, We are pleased to inform you that your manuscript 'Confidence Intervals by Constrained Optimization – an Algorithm and Software Package for Practical Identifiability Analysis in Systems Biology' has been provisionally accepted for publication in PLOS Computational Biology. Before your manuscript can be formally accepted you will need to complete some formatting changes, which you will receive in a follow up email. A member of our team will be in touch with a set of requests. Please note that your manuscript will not be scheduled for publication until you have made the required changes, so a swift response is appreciated. IMPORTANT: The editorial review process is now complete. PLOS will only permit corrections to spelling, formatting or significant scientific errors from this point onwards. Requests for major changes, or any which affect the scientific understanding of your work, will cause delays to the publication date of your manuscript. Should you, your institution's press office or the journal office choose to press release your paper, you will automatically be opted out of early publication. We ask that you notify us now if you or your institution is planning to press release the article. All press must be co-ordinated with PLOS.

Open letter on the publication of peer review reports
PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.
We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
