Annotation of the columns:

1. all_ATAC_peak_category_and_location.csv

peak: ATAC peak name
chr: Chromosome
start: Start postiion of the ATAC peak
end: End position of the ATAC peak
summit: Summit position of the ATAC peak

category: Category of the ATAC peak
Group1: Accessibility lost in MZnps
Group2: Accessibility significantly reduced in MZnps
Other: Accessibility not significantly different between WT and MZnps
Upregulated: Accessibility significantly increased in MZnps

location: Location of the ATAC peak
Promoter: ATAC peaks located at promoter regions (+/- 500bp TSS) of genes/transcripts
Active enhancer: ATAC peaks not located at promoter regions of genes/transcripts and overlap with H3K27ac peak (extended 200bp on each side)
Other region: ATAC peaks not located at promoter regions of genes/transcripts and without overlap with H3K27ac peak (extended 200bp on each side)
