distance

(1-3) CpG_chrm, CpG_beg, CpG_end: the location of the target. CpG_beg is 0-based coordinate and CpG_end is 1-based. The coordinates should have a span of 2 nucleotides for CpG probes, or 1 nucleotide for CpH and SNP probes.
(4) probeID: Probe ID
(5) CTCF: CTCF bindig site in the format: chr:beg-end
(6) distance: distance to CTCF binding summit
