chromosome begin end chromosome tss tss gene score . strand RGB

begin - start of DHS of cCRE/enhancer
end   - end of DHS of cCRE/enhancer

tss    - GENCODE v33lift37 TSS of gene
gene   - ENSEMBL gene name
score  - 0-1000 score based on fraction of links present across biosamples in tissue group.
         Only gene-enhancer links with score above 500 (i.e. present in at least half of biosamples per tissue group) are present.
.      - not used
strand - strand of gene
RGB    - comma separated list of RGB values for group corresponding to EpiMap metadata
