treeReaderRec->GetEntries() not working correctly in Analysis_Ex.cc

[anonymous]

Hi,

I have run 500k monojet events using MadGraph, fed them to pythia 8, with the showered events output to LHE files, and fed into Delphes. Running the trigger selection, all 500k events are seen properly. However, when I run Analysis_Ex it says that the chain contains 1M events and performs the analysis as if there are actually that many events available for analysis.

At first the analysis outputs events that pass cuts at slow rate (as I would have expected) and then after some number of events it reports a higher frequency of events passing cuts. Any ideas what could be happening here? It appears to me that treeReaderRec->GetEntries() is not retrieving the correct number of entries for some reason.

Hi,

This is the first time such an issue is reported. I'll try to have a look at it. Is there any way you could share your events so that we can run on them ?

Thanks,

Jerome
