Hi, I ran the evio conversion on a 5772.0 file yesterday and everything was fine. I’m now trying to run in and I fail with: Wed Sep 09 17:51:48 PDT 2015 org.hps.evio.EvioToLcio run INFO: Opening EVIO file ../data/engrun/hps_005772.evio.0 ...

I changed detectors and that didn’t matter. I didn’t touch that file. Any ideas what this can be?
