Use a tree friend (see TTree::AddFriend).

Cheers,

Dear Rooters,

I have two files "file1.root" and "file2.root". Each file contains a tree
"T1". file1.root is calculated by a different algorithm. I want to compare
the contents of the tree in each file such that the resulting histograms
are normalized. How do i do it?




Dennis
