Distribution of mean ChIP-seq signals of nucleosome and three types of HM, including H3K36me3, H3K9me3 and H4K20me1, on CEs and ±250 bp flanking regions. The ChIP-seq signals were averaged over each portion of CE samples, which were partitioned into high and low portions according to inclusion levels. The upper and lower half parts correspond to the signal distributions for Gm12878 and K562, respectively.
