- H3K4me1- primed enhancers – broad peaks
- H3K4me3-promoters – sharp peaks
- H3K9me2-transcriptional repression – broad peaks
- H3K9me3-heterochromatin – broad peaks
- H3K9ac-actively transcribed promoters – sharp peaks
- H3K14ac actively transcribed promoters
- H3K27me3-polycomb repression, silenced genes – broad peaks
- H3K27ac-activate promoter or enhancer – sharp peaks
- H3K36me3-gene bodies – broad peaks
- the peak type may be mixed, double check by IGV
