I have multiple (n) bed files with identical intervals and one unique information column. I would like to combine these into one bed file with n information columns.
chr start stop col.foo chr1 1 10 foo chr1 20 30 foo
chr start stop col.bar chr1 1 10 bar chr1 20 30 bar
chr start stop col.foo col.bar chr1 1 10 foo bar chr1 20 30 foo bar
I tried using bedtools merge, but don't see an obvious solution. This only keeps the information column of one of the files:
bedtools merge -c 4 -o collapse -delim = "\t" -i file1.bed -i file2.bed
