Hello, I wanted to add a little more information for anyone willing to look into this. The original tritrig file I used can be found at: /work/hallb/hps/ > mccaky/tritrigv2_5mrad_z-0pt5mm_HPS-PhysicsRun2016-v5-3-fieldmap_globalAlign_9999-spaced.slcio The readout and recon files can be found at: /work/hallb/hps/mccaky/tritrigReadout_Pair1.slcio > /work/hallb/hps/mccaky/tritrigRecon_Pair1.slcio The relevant collections in these files are: - Raw Hits >> Collection Name: "EcalReadoutHits"; Type: RawTrackerHit - Converted Hits >> Collection Name: "EcalCalHits"; Type: CalorimeterHit - GTP Clusters >> Collection Name: "EcalClustersGTP"; Type: Cluster - Clusters >> Collection Name: "EcalClusters "; Type: Cluster These files were created with > > /steering-files/src/main/resources/org/hps/steering/readout/PhysicsRun2016TrigPairs1.lcsim for readout (noise was disabled for the SVT and calorimeter) and /steering-files/src/main/resources/org/hps/steering/recon/PhysicsRun2016FullReconMC.lcsim with no changes for recon.
