Dear Alfredo,
Thank you for your email. I am using "stuprf" routine to storage the
"mother" momentum of particles leaving the target. I found an example on
the discussion list but most of the time the particles leaving the
target have generation numbers greater than 2 so the mother information
is not the primary interaction (generation==1). I have attached my
version of "stuprf.f". Could you also explain what exactly is "PNPPRMR"?
Please let me know if I misunderstood something or what I am missing in
the routine to storage the primary vertex in addition to the mother
information.
Thank you very much,
Francisco
