RE: [ROOT] Chain to Tree

Hi Rene,

Actually, I need to use the chains, but when I'm trying to extract some
branches to new tree like copytree.C example it does not work. I'm 100% sure
that all branch addresses are set up. No way to do it with chains? ROOT
version is 3.01/06.

Thank You!

Hi Andrey,

Use TTree::CopyTree
