Why does TrigSim crash when running on events that have been reco-ed?
TrigSim will usually crash on reco-ed data coming from the online machines because the default there is to not keep the raw data chunk (RDC). Please note that this is also the default when you run it yourself…no RDC! TrigSim needs this RDC to run properly. Try reco-ing the raw events yourself, setting reco to keep the RDC. Alternatively you can just run TrigSim on the raw events.
