Re: Special Cuts

Dear Ivana,

I'm using physics list LHEP_EMV or CHIPS. I tried to reproduce the same code from the example E03, then I set the cuts in my DetectorConstruction.cxx at the end of
DetectorConstruction::ConstructGeometry(), right after gMC->SetRootGeometry().
Eventually, I could reproduce the error in the example E03, but until this time only with the physics list LHEP. However in the table that resumes the cuts (at the beginning of the run), they seem to be correct.
On the contrary LHEP_EMV and CHIPS, that give me the error in my simulation, run well in the example. Of course, in the same table at the beginning of my simulation, the cuts are ignored.

Thank you,
Florian
