closeReferee comments: Referee 2 (Gabor Balazsi)

Referee 2's review (Gabor Balazsi):
In this manuscript, Jupiter and VanBuren 1) present a web-based tool (StarNet) for visualizing cross-correlation based mouse gene networks; 2) compare the distribution of cross-correlation coefficients and genecentric networks for the full dataset and a cardiac cohort.
The manuscript has no major faults, and StarNet might be a useful tool for biologists looking for candidate genes interacting/regulating a gene of interest. I believe the manuscript could be improved if the authors addressed the following comments:
- Some parts of the manuscript are not clear. For example, the Results start off with a sentence about "a genecentric distribution", but such a distribution has not yet been defined. The statistical tests that were used to determine the p-values should be mentioned in parentheses after the p-values. In the Introduction a reference to the source of data should be given. In general, some information from the Methods should appear in the Results too, to make the manuscript clear.
- On page 4, 3' is followed by "prime"
- On page 4, there should be a reference after Dai et al.
- The first reference has a typo in it
- How were the ranges of correlations (indicated by various shades of blue under the network) determined? Was the full range of genecentric correlations equally partitioned?
- It would be interesting to see if the differences observed for the cardiac cohort hold for another tissue-specific subset
- It would be interesting to discuss if the difference between the networks in Fig. 3A and 3B could be somehow quantified.
