Is it 'prestart' and 'go' events ? ----- Original Message ----- From: Jeremy I. McCormick <[log in to unmask]> To: hps-software <[log in to unmask]> Sent: Thu, 24 Oct 2013 04:38:44 -0400 (EDT) Subject: null EVIO events in test run data Hi, I’m back to doing some work on the monitoring app, and I’m seeing something strange... I have noticed that in the EVIO files for the test run, there are always a few events in the beginning of the run for which the EvioReader returns a null EvioEvent without throwing any kind of error. Since this class is a complete black box to me, I wonder if anyone can tell me why this might be happening? Does the problem sound familiar? It seems I can simply skip over these problematic events without any adverse effects, but ideally this situation should result in an exception being thrown. I would like to be able to pre-check events for characteristics that will cause this problem and discard them if this is going to happen, but right now I can’t tell what exactly is going wrong. For now, I’ll just have the app print a message to the log table. Thanks. —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 ######################################################################## 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
