Dear Anton,
I managed to compile the MGREAD program, but when I try to run it, it
prints only a few lines and I get this error:
'Fortran runtime error: I/O past end of record on unformatted file'.
About the information: for all the events, I need to know the position
of the interactions of the source pions in the target, then dump of a
list of the numbers, momenta and directions of the directly produced
secondaries. In fact, I intend to study the physical background of
hadronic interactions for charm mesons' decay measurement in nuclear
emulsions.
Thank you for your help.
Best regards,
Antonio.
