Data frames of features (peaks, genes...) coordinates on genome.
A data frame with the following columns:
CHROM
Chromosome names in character format, e.g. "15", "X" (character
).
start
Start positions (integer
).
end
End positions (character
).
id
Unique identifiers, e.g. gene name "CDH1" or peak identifier
CHROM_start_end "1_1600338_1600838" (character
).
