I am trying to use the TChain and AddFriend methods. This is what I do:
TChain *chainbm = new TChain(“bmtree”);
TChain chainsr = new TChain(“NtpSt”);
None of them seem to work, I get an error message:
Unknown TChain bmtree or
Unknown TChain chainbm
Both the chains have the same number of entries.
- thanks Debdatta.
