Hi,
I am trying to create an analysis program on the root tree that I have created. I have used MakeSelector to make a source and header files.
So far I have added a simple std::cout statement to the Process() function.
fChain->GetTree()->GetEntry(entry);
if(nMuon!=0)
std::cout << "muon charge is " <<Muon_charge[0] << std::endl;
I am using a simple script to run the analysis:
#include
void run_bprime_analyzer()
{
TChain* fChain=new TChain(“ntuplizer/bprime_tree”);
// farm data
fChain->Add("/cms/data11/bprime/bkgrnd/ntuple.root"); fChain->Process("/$HOME/CMSSW_1_6_9/src/bprime_tree.C++");
}
However, I am getting the following errors:
root [0] .x run_bprime_analyzer.C

Error in : Dictionary generation failed!

Info in : The compiler has not found any problem with your macro.
Probably your macro uses something rootcint can’t parse.
Check root.cern.ch/root/Cint.phtml?limitations for Cint’s limitations.
Error in TSelector::GetSelector: file /$HOME/CMSSW_1_6_9/src/bprime_tree.C++ does not have a valid class deriving from TSelector
None of it make any sense to me. Can somebody please explain what am I doing wrong?
thank you very much,
Dmitry.
