Balancing for mcool files while loading contacts？

[MaybeBio]

Hi,
I recently worked on multiple cool files between GENOVA and HiCExplorer.
I first converted the matrix file from raw hic-pro format to cool file without Normalizing，
Then i use HiCExplorer's hicNormalize and hicCorrectMatrix (--correctionMethod KR)，

what i did using hicNormalize is this：

then what i did using hicCorrectMatrix (--correctionMethod KR) is this：

so i now have mcool files normalized using KR amongst multiple samples，what i confused is how do i set some of these parameters

1,do i need to set scale_bp=NULL which was mentioned in #356,
2,do i need to set balancing=FALSE cause i see description "
balancing | TRUE (default) will perform matrix balancing for .cooler and KR for.hic."
but i have already done KR normalizing to mcool files ？
Or are there any other Settings I need to be aware of

Thanks a lot,
Best
