Hi ROOTers,
According to examples I do the folloging:
root [0] TChain chain("di-muon ntuple");
root [1] chain.Add("CA3871_jpsi.root");
I get this:
Error in <TChain::Add>: cannot find tree with name di-muon ntuple
although I am pretty sure that this ntuple exists in the file.
if I use TBrowser to open file I am able to get to that ntuple and
look into contents.
What am I doing wrong?
