 some note 
"Your directories included the codes I developed for SPD background rate analysis, and there do include cuts from EC. 
For the MRPC, I  don't have a well maintained analysis code but this one can be a good starting point:
/w/halla-scifs2/solid/yez/sidis/mrpc_test/scan/GetRate_Background.C
What we need to do is to combine the cuts from three detectors. For EC, we know the radial dependent energy cut, 
and for SPD, we can use the MIP cut. However, for MRPC, we haven't have a good cut yet. 
I initially did a quick study by putting the detailed layers of MRPC gas+glass, and found out that 
if I required two gas layers out of 10 layers create electrons, we can select good electrons."

work-directory for the SPD study is located in the following link: /w/work6501/yez/solid/spd_study
I prepared a quick README for you to understand the workflow. I also included some slides related to this study. I hope they can be your starting point or references. Let me know if you have questions.
