Question

First I have produced tag_1_pythia8_events.hepmc.gz in MG5_aMC_v3_3_2  with Pythia8. Then I used Delphes v3.5.0 ./DelphesHepMC2 to convert HEP file into root files. I have saved genjets module FastJetFinder GenJetFinder { set InputArray NeutrinoFilter/filteredParticles set OutputArray genjets set JetAlgorithm 6 set ParameterR 0.4 set JetPTMin 1.0 }  "add Branch GenJetFinder/genjets GenJet Jet"in delphes card.  This is my loop in expert mode if (event.mc()!=0) { } if (event.rec()!=0 ) {std::cout << "Number of GenJets: " << event.rec()->genjets().size() << std::endl;} I am not getting error but genjets size is zero and there is no events for that. But I can see the events in delphes root files. Could you please help me in this case?

Hi,

You should run Delphes from MA5 directly.

Dear Bejnamin,

Thank you for your reply. But I did not understand how I have to run delphes from MA5. Could you please elaborate it.

Thank you in advance, Meena
