Hi,
It is strange that in the header file the same branch name (RN) is used in
all the calls to SetBranchAddress. This means to me that the address is
overwritten with each call.
To go any further, I would have to look at your data file Can you send me
one?
Suzanne
tuple->SetBranchAddress("RN",&RN_Pzt4);
tuple->SetBranchAddress("RN",&RN_chit4);
tuple->SetBranchAddress("RN",&RN_masst4);
tuple->SetBranchAddress("RN",&RN_pidt4);
tuple->SetBranchAddress("RN",&RN_);
