Hi, sorry to bother again, but I have again some problems to run reconstruction on montecarlo data. If I set run number 0 (which I believe is what I should do, since next step will be to provide a new compact.xml and I don't want it to be read from the conditions db), I get an error upon reading svt time constants: Sun May 31 12:18:05 CEST 2015 org.hps.conditions.database.DatabaseConditionsManager findConditionsRecords FINE: found 0 conditions records matching tag null java.lang.RuntimeException: No conditions were found with key: svt_timing_constants at org.hps.conditions.database.AbstractConditionsObjectConverter.getData(AbstractConditionsObjectConverter.java:105) ... etc If, as suggested by Matt, I set the run number to 5632, svt timing constants are ok but I get another error, as follows: INFO: Event 5 with sequence 0 May 31, 2015 12:16:41 PM org.hps.recon.ecal.cluster.ClusterDriver process SEVERE: There is already a cluster collection called EcalClusters java.lang.RuntimeException: Cluster collection already exists in event. at org.hps.recon.ecal.cluster.ClusterDriver.process(ClusterDriver.java:228) at org.hps.recon.ecal.cluster.ReconClusterDriver.process(ReconClusterDriver.java:98) ... etc any idea on what should I do? My steering file is HPS2014OfflineNoPileupRecon.lcsim as it comes from the trunk (apart from the gbl output driver), everything freshly updated and built.
