Hi,
You could do this using a script combining the output of
the "measure contacts" commands with your own code to update
the per-atom Beta field per-collision. You can probably get
"measure contacts" to do the hard part of the work, after which you
will just need to shuffle the output to the beta fields of the affected
atoms.
Cheers,
John Stone
