Weights per event in a tree

ROOT
1

Hello,

I was wandering if there is a quick way to extract a number of events satisfying a given cut (events have weights saved in one branch, so GetEntries(CUT) doesnt work). I know i can do this through drawing a histogram (with the weight*CUT) and then integrating it, but isn’t there a faster and easier way?
I am using root 6.08.

Regards,
Maks
