[Clas12_software] simulation_reconstruction_issue

[Joshua Artem Tan]

Dear All,


I am reconstructing simulated files (gemc 4a.2.4) with coatjava 5b.6.1 
and the reconstruction hangs up (I'm running in the interactive farm). I 
didn't have this problem with 5b.6.0. The only thing I changed for both 
versions was this part of the yaml file:

  services:
     DCHB:
       torusMap: Symm_torus_r2501_phi16_z251_24Apr2018.dat
       solenoidMap: Symm_solenoid_r601_phi1_z1201_2008.dat
       useStartTime: "false"
       geomDBVariation: default
       constantsDBVariation: default
     DCTB:
       geomDBVariation: default
       constantsDBVariation: default

The following is the error message I am getting:

2018-08-23 15:07:20.471: Error in 129.57.70.22%7400_java:joshtanj:DCHB

Does anybody have any idea how to get around this problem?


Thanks,


Josh
