Hi @dnevill I meant the code depending on the fscoring! anyway, By searching “fScoring”, I just found it B1SteppingAction.cc and I commented all the file (see attachment)
B1SteppingAction.cc (3.1 KB)
Then I modified the example B1.in file to have just a 45GeV positron beam hitting on the target (see attachment) , then I tried to compile and run the exe but I got this error
