I googled some and found this way.

Check single entry of a tree is in TCutG

Hello, I would like to check if a single entry of a tree is on TCutG. for (Long64_t i=0; i<nentries;i++) { tree->GetEntry(i); if(!tree->Scan(“Mass”,TcutG,"",1,i)) continue; …Use that single tree entry, not only one branch… } The problem is when I use Scan(), every time I get for all the entries: Row * Mass * Is there an option in Scan not to show these ********, or is there an easier way to check if the entry satisfy the cut. Thanks.

I can just loop over all entry and check if it’s in the CUTG or not.
If you have any better idea, please let me know.

Thank you for your replay.
