Subject: AMBER: ptraj hbond

Hi Everyone,

I am a new user to the hbond facility within ptraj (version 9). I am
studying a single organic molecule in TIP3P water and I want to use
ptraj to analyze INTRAmolecular hydrogen bonding. In my simulations,
the organic molecule is contained within a single residue, which
poses a problem since ptraj's hbond command does not count intra-
residue interactions. Does anyone know of a way to use ptraj to
count intra-residue interactions? My guess is that it would involve
a fairly simple modification to the ptraj code, so if anyone could
help me zero in on the section that controls the residue restrictions
in the hbond counting I would appreciate that. Any other suggestions
would be greatly appreciated, too.

Thanks!
