KR issue with mcool format while calling loop

[MaybeBio]

Hi,
I recently worked on cool files between mustache and HiCExplorer.

what i did using hicNormalize is this：

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

the question is：

do i need to set -norm KR or just use the default while loop calling
