John,

What I thought the code was doing currently is the following:

Celeg produces MCTK and MCVX banks.
GSIM reads the PART bank, if it is not found it will use the MCTK and MCVX.
RECSIS reads the output of GSIM producing a PART bank, it keeps MCTK and
MCVX banks if they already exist.

In this scheme, after running Celeg -> gsim -> recsis I can compare the MCTK
bank from Celeg (what I started with) to the PART bank I finally ended up
with.

If I want to run: Data -> RECSIS -> GSIM
Then GSIM reads the PART bank and I can check whether particles actually
found in the data also make it through the Monte Carlo.

In the first scenario, it may actually be preferred that celeg produce MCTK
and MCVX banks. Which also saves you from making any changes to PART or the
way GSIM reads it's input.

So in the end, I think it may be better for reanalysing data that had been
through recsis if we leave things as they are. I would like to see if our
PWA friends have any comments on this.

Best Regards,

Maurik
