Pearson correlations of distance-normalized Hi-C interaction frequency maps corresponding to various chromosome regions in GM12878 and HCT-116 cells. On top of each Hi-C map from top to bottom: fold change over control shown for H3K27ac (red), H3K27me3 (blue), and H3K9me3 (green); PC1 component from PCA (black), and k-means cluster classifications corresponding to compartments A (red), B (blue), C (green), and D (black).
