fNClusterRange

Hi,
I’m using ROOT version 5.29/01.
If I apply my selector on a tree, I get the following warning:

Warning in TStreamerInfo::Compile: Counter fNClusterRange should not be skipped from class TTree

Apparently, I don’t find any error or strange behaviour in the output tree.

I would like to know if I really need to fix this warning anyway, or If it is completely irrelevant.

Thank you.
Vincenzo.
