Hello Nathan,
I went to "detector-data/detectors/HPS-PhysicsRun2016-Hodoscope-v3-2pt3-fieldmap/SamplingFractions/" and copied "Ecal.properties" to "Hodoscope.properties" and then recompiled. The error still occurs, however.
I assume that it is correct to name the properties file the same thing as the detector name in the compact.xml? (It is "Hodoscope" here.) This appears to be what was done for the calorimeter.
This is all on the iss40 branch, for the record.
Thanks,
Kyle

Hi Kyle,
Looks like your error is really in lcsim, not hps-java, and I don’t think lcsim cares about hps’s database?
It might be you just need a X.properties file in the SamplingFraction subdirectory for your detector (where X is the name of your hodoscope detector in the compact.xml), just a guess ...
