Dear Alessandro,
please keep the discussion on the mailing list, to help other as well.
Yes, the partial code I provided in my previous mail replaces it in place.
So bash script in theory will create a separate subfolder for each job, copies the "master" input file there, replaces the RANDOMIZ line, and starts the FLUKA run.
Kind regards,

So you suggest to substitute the RANDOMIZ card directly in the fluka
input file?
Best regards, Alessandro Calamida.
