Hi, I am looking specifically at the ReconParticleDriver.java to readjust my corrected energy and position calculations that were output in the cluster collection. I am running into an error that I am not sure I understand (maybe it is simple). The current code is using the Cluster collection. My output collection is HPSEcalClusterIC which is an extension as Cluster->BaseCluster->HPSEcalClusterIC. The problem I am running into is that certain methods (for example: makeReconstructedParticles()) will not take an input cluster list from my collection. I thought when I extended it originally it would be good, but apparently not. Do I need to write an Override to include my cluster list type or is there a simpler solution? -- Respectfully, Holly ######################################################################## 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
