Figure 1

Relative Hi-C contact probability maps. Whole-genome (A,D) and chromosome 19 (B,E) maps at a 1 Mb resolution for sperm cells and fibroblasts. The color of each dot represents the log of the interaction probability for the corresponding genome bins. The graphs under the heatmaps show E1 values for chromosome 19 in sperm cells and fibroblasts. The two-dimensional contact correlation matrices constructed as in [10] (C,F) demonstrate the characteristic plaid patterns for both sperm cells and fibroblasts.
