Hello, I ran the cn.mops function from the cn.MOPS package. the result summary looks something like this:

GRanges object with 1377 ranges and 4 metadata columns:

Can someone please explain the "median" and "mean" columns? What are the values in these columns? mean/median of what? How should I interpret them? I came across this old thread, but the answer there is still not clear to me.

Thanks!
