MACS2 bdgdiff output empty

[MerFer]

Hi all,

I am trying to run macs2 bdgdiff

my command line

macs2 bdgdiff --t1 KO_treat_pileup.bdg --c1 KO_control_lambda.bdg --t2 WT_treat_pileup.bdg --c2 WT_control_lambda.bdg --d1 33438858 --d2 38068471 -g 60 -l 120 --o-prefix diff_KOvsWT

Everything works fine and I get no errors etc.,
b the result files are empty.
Do I miss something?

Thanks a lot,

Maria
