Hi, I'm getting a null pointer error when I run recon with this command line. ./evio2lcio.sh -r -x /org/hps/steering/recon/EngineeringRun2015FullRecon.lcsim -DoutputFile=hps_005772 -d HPS-EngRun2015-Nominal-v1 /nfs/slac/g/hps3/data/engrun/evio/hps_005772.evio.0 Exception in thread "main" java.lang.NullPointerException at org.hps.recon.utils.TrackClusterMatcher.isMatch(TrackClusterMatcher.java:207) at org.hps.recon.particle.ReconParticleDriver.makeReconstructedParticles(ReconParticleDriver.java:264) It seems like the track-cluster matcher is not able to find the track state at the ECal face (could be caused by a problem upstream in another Driver). The EngRun2015ReconTest seems to be fine but it uses the EngineeringRun2015FullRecon_Pass2.lcsim steering file and not this one. Should I just switch to using the Pass2 steering for now? --Jeremy ######################################################################## 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
