Analysis of mouse ENCODE histone ChIP-seq datasets. (a) List of combinatorial patterns identified by jMOSAiCS. Patterns 1 to 6 are also identified by chromHMM. (b) Changes in chromatin states between G1E and G1E-ER4+E2 cells for DNA segments occupied by GATA1 in the latter cells. (c) Heatmap of normalized raw data for a group of 311 GATA1-occupied segments identified to switch from 1101 in G1E cells to 1111 in G1E-ER4+E2 cells by jMOSAiCS. Enriched regions (excluding segments longer than 1,400 bp in size) identified across different marks are aligned and depicted in between the dashed lines.
