Dear Felix,

I don't know whetherit possible or not to switch on and off different
kinds of nuclear interactions, but you can score the dosage separately
from inelastic interactions like (n,p), (n,alpha) by using STUPRF and
COMSCW user routines.

Depending on different interactions types from (EVTFLG) header you can
score inelastic and elastic events with different secondaries.

If you need an example, fill free to ask.

Best regards,
Mikhail
