Hello Nathan, et al.,
I've tracked down the problem to a mismatch in how we read and write the SIOCluster from within hps/lcsim and natively from lcio (both java and C++). I can read the files with a locally modified version of the lcio code, both with C++ and java, but I need to figure out how best to solve the problem before proceeding with a fix.
Apologies for the delay,
Norman

Subject: problem reading latest slcio files
Hi Everyone,
Has anyone successfully used the C++ API to read the latest pass0 SLCIO files:
/mss/hallb/hps/engrun2015/
In my analysis code, IO::LCReader->readNextEvent() is always returning zero.
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
