Distribution of reads around CpG Islands and gene body. (a) Distribution of reads around CpG Islands; (b) Distribution of reads around gene body. The upstream and downstream 2 kb regions were split into 20 equal regions. In the gene body, each gene was split into 40 equal regions. For each region, the normalized number of reads was calculated. The “Y” axis is the average of the normalized depth for each region.
