Extended Data Fig. 4: Repeat enrichment in H3K27ac peaks.

Heatmaps showing enrichment of all repeat subfamilies at distal H3K27ac peaks compared to that in random peaks in oocytes, early embryos, and mESCs. The H3K27ac enrichment was calculated as a log2 ratio for the numbers of observed peaks overlapped with repeats divided by those for random peaks (shuffled peaks with lengths matched).
