Hi, Have some issues getting the MC simulation to run. I’m running readout and recon over some 1.1GeV 40MeV A' MC files locally with the trunk. Slic file is here: /nfs/slac/g/hps3/users/phansson/ap1.1gev40mevall_1_200ux40u_beamspot_gammactau_0cm_30mrad_SLIC-v04-00-00_Geant4-v10-00-02_QGSP_BERT_HPS-EngRun2015-Nominal-v1.slcio I’m using Nominal-v1 detector and I simulate readout with: java -jar target/hps-distribution-3.3.1-SNAPSHOT-bin.jar ../kepler2/hps-java/steering-files/src/main/resources/org/hps/steering/readout/EngineeringRun2015TrigPairs1.lcsim -Ddetector=HPS-EngRun2015-Nominal-v1 -Drun=2000 I see 245 accepted events out of 10k events which is much lower than I would naively expect? I then run recon with: java -jar target/hps-distribution-3.3.1-SNAPSHOT-bin.jar ../kepler2/hps-java/steering-files/src/main/resources/org/hps/steering/recon/EngineeringRun2015FullRecon.lcsim -DoutputFile=outfiles/ap1.1gev40mevall_1_200ux40u_beamspot_gammactau_0cm_30mrad_SLIC-v04-00-00_Geant4-v10-00-02_QGSP_BERT_HPS-EngRun2015-Nominal-v1-recon -i outfiles/ap1.1gev40mevall_1_200ux40u_beamspot_gammactau_0cm_30mrad_SLIC-v04-00-00_Geant4-v10-00-02_QGSP_BERT_HPS-EngRun2015-Nominal-v1-readout.slcio And I basically get to the 2nd event and then it just hangs there for 5-10mins. Are these the right steps with the latest and greatest sw? Any ideas? /pelle ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
