[Clas12_verystrange] Quick MC question: gcard for fall 18 positive

Hi Michael,

You can choose appropriate gcard accordingly for different experiment configuration from https://github.com/gemc/clas12Tags/tree/master/4.4.1/config

I believe for  just to change the torus polarity, you want to edit the line  <option name="SCALE_FIELD" value="TorusSymmetric, -1”/>  in your gcard to <option name="SCALE_FIELD" value="TorusSymmetric, +1”/>  (note torus -1 means e- Inbending) and don’t forget to match the same torus polarity while converting gemc output to hipo format (evio2hipo decoding step).

For the detail help on how to run simulation please follow the link below from HOWTOs tab from CLAS12 Centralized Software Wikipage ::

Hi,

For the negative field fall 18 and spring 19 data I have used
clas12-default.gcard

What gcard should I use for the fall 18 positive field data?

Thanks for your time!

Sincerely,
Michael
