Chromatin state maps data were obtained from the NIH-initiated Roadmap Epigenomics Project2, which we used to determine genomic location and infer DMR function. A chromatin map of 15 different states constructed from HeLa-S3 cervical cancer cells including five histone marks (H3K4me1, H3K4me3, H3K36me3, H3K27me3, and H3K9me3) was downloaded to as HeLa cell reference (Epigenome ID: E117) (Roadmap Epigenomics Project3). The significance and fold enrichment of DMR to each state was calculated as previously reported (Wahlberg et al., 2016).
