Hi Kathrin,

To use the branch that contains object the type 'vector<TLorentzVector>' you currently need to make
sure to generate the dictionary for it. So try with:

• cat analyze.h #include <vector> #include <TLorentzVector.h> #include <iostream> #include <fstream>

#ifdef __MAKECINT__
#pragma link C++ class vector<TLorentzVector>+;
#endif

• cat analyze.C double analyze(){ cout<<"Event properties: "<<eventNumber->size() << " " << eventNumber[0] <<endl; cout<<"jet4mom size: "<< jet4mom->size() << '\n'; if (jet4mom->size() > 0) cout << jet4mom[0].Px() << endl; return eventNumber[0]; }

  ---

Cheers,
Philippe.
