Figure 1: (A–C) Example of annotation of chromosome 3R region by transitional gamma. For a given Hi-C matrix of Schneider-2 cells (A), TAD segmentations (B) are calculated by Armatus for a set of gamma values (from 0 to 10, a step of 0.01). Each line in B represents a single TAD. Then gamma transitional (C) is calculated for each genomic region as the minimal value of gamma where the region becomes inter-TAD or TAD boundary. The blue line in C represents the transitional gamma value for each genomic bin. The plots (B) and (C) are limited by gamma 2 for better visualization, although they are continued to the value of 10. Asterisk (*) denotes the region with gamma transitional of 1.64, the minimal value of gamma, where the corresponding region transitions from TAD to inter-TAD. (D) The histogram of the target value transitional gamma for Schneider-2 cell line. Note the peak at 10.
