Hi Alexandros,

if I understood well your question, you are looking for something like in /tutorial/rho/tut_ana.C

for (j=0;j<jpsi.GetLength();++j)
if (theAnalysis->McTruthMatch(jpsi[j]))
hjpsim_reco->Fill( jpsi[j]->M() );
hjpsim_true->Fill( jpsi[j]->GetMcTruth()->M();

Here the example is related to the J/psi mass, reconstructed through pi+ pi-. jpsi = name of the combined list pi+ + pi-. hjpsim_reco and hjpsim_true are 2 histograms.
Is this what you asked?

[...there are never stupid questions Smile )

cheers, Elisabetta
