Additional file 4: Figure S4. Epigenetic states for each site class. (A) For each site class of iMK, Ery, Mon, and Neu, total length of the regions with each epigenetic state for each cell was plotted. To highlight the differences, epigenetic state 0 (all the epigenomes are quiescence), which was most abundant for all cells, was not displayed. (B) Heatmap of each epigenetic state, which is based on the information provided by the VISION project ( https://usevision.org/data/mm10/IDEASmouseHem2019/ideasVisionV20p8Seg.statesig.para ).
