Hello Jan, first of all, I have absolutely not a clue about your specific segmentation fault problem. However, you claim your code include the lines > > Added G4EventManager as protected member and in the EndofEventAction() I did > > if (aSteppingAction->GetGoodEvent() == true) > EventManager->KeepTheCurrentEvent(); So, I created my own version of it using geant4.9.4.p02 and it works nicely. So my best guess is that you are not initializing correctly the pointer to the Eventmanager and/or the aSteppingAction. This is what I did and worked, in the BeginOfEventAction(): ((SteppingAction*)(G4RunManager::GetRunManager()->GetUserSteppingAction()))->SetKeeper_flag(false); [to reset the variable every event] and in the EndOfEventAction(): if(((SteppingAction*)(G4RunManager::GetRunManager()->GetUserSteppingAction()))->GetKeeper_flag()) G4EventManager::GetEventManager()->KeepTheCurrentEvent(); [in the SteppingManager there is a place where I set the keeper_flag only for those events I want to store.] To visualize the events with DAWN I use this: /vis/open DAWNFILE /vis/drawVolume /vis/scene/add/trajectories /vis/disable /run/beamOn 20 /vis/enable /vis/reviewKeptEvents I hope this is not necrobumping and that by now you have already solved your problem. Anyway since I saw no reply to your question I thought it will be nice if someone find the answer right next to the question. Best regards, /Pico
