setenv JANA_CALIB_CONTEXT "variation=mc calibtime=2017-01-31”

I suggest starting with the "mc_generic" variation, which provide a default run-independent set of calibrations & conditions.  When you're ready to generate simulations that correspond to actual data taking, you can use the "mc" variation.

The program normally outputs the hdgeant.hddm file but throws this error during the smearing process. I wonder what I need to change in my environment to get this to work. Currently my JANA_CALIB_URL = sqlite:////home/gluex/ccdb/sqlite/ccdb_2017_02_02.sqlite. I tried the latest version: ccdb_2017_02_07.sqlite as well, but it didn’t work.
