Figure 2: Pairwise correlations of marks and expression changes in gene bodies. Heatmaps are shown for regulated genes from the filtered intron-containing (IC) sets for low (LCG) (a) and high (HCG) (b) CpG promoters. The color represents the value of the Pearson correlation coefficient between the zscores for every pair of attributes. Both panels use the same scale, indicated above. For expression (RNA-Seq), the z-scores of the Up and Dw transcript loci were used to calculate the correlation.
