To increase transparency, PeerJ operates a system of 'optional signed reviews and history'. This takes two forms: (1) peer reviewers are encouraged, but not required, to provide their names (if they do so, then their profile page records the articles they have reviewed), and (2) authors are given the option of reproducing their entire peer review history alongside their published article (in which case the complete peer review process is provided, including revisions, rebuttal letters and editor decision letters).
In its original submission to the InCoB2013 meeting, this manuscript had received two contradicting comments. Although PeerJ recommends the handling editor to collect at least four reviews, I hereby make an exceptional decision of acceptance with those two reviews partly because I admit that the authors' replies to the reviewers' comments are reasonable and partly because I also have a positive opinion about the suitability of this manuscript as a reviewer.
