I have the same problem. They didn't appear to contain any events when using Jas3 or Root.

Rafayel has the same issue, and also says hps_dump_event from the DST doesn’t work (which presumably uses the same API). The lcio print command from here doesn’t work either: svn://svn.freehep.org/lcio/ On some files I get an “Out of Memory” error after this: at hep.lcio.implementation.sio.SIOParticleID.<init>(SIOParticleID.java:26) On others I get: Exception in thread "main" java.lang.NegativeArraySizeException at hep.lcio.implementation.sio.SIOParticleID.<init>(SIOParticleID.java:26) None of the above problems existed on 2014 data nor on data we reconstructed with ecal-only over the previous weeks. And now we can’t analyze data. Any ideas to fix this? -Nathan ######################################################################## 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
