Figure 2

Histogram of the correlation coefficients of the gene expression time series between all the genes selected with the change point analysis in the D. melanogaster dataset. In the NY-controls (top left) the histogram resembles a Gaussian distribution slightly skewed towards positive correlation values. When considering the expression ratio Y-treatment over NY-control (top right) the distribution becomes bimodal and genes tend to be either strongly correlated or anti-correlated. These results have been validated by reshuffling the time points independently for each gene. In both cohorts this leads to a Gaussian distribution (bottom row).
