[gmx-users] Control Atoms for Hydroxide ?

[Marc Charendoff]

Sorry for bringing up the hydroxide ion question again, but are there any hints as to how to place a single hydrogen on the oxygen atom? Can I somehow assign control atoms outside the hydroxide anion as a means of reference for the required  ffG43a1.hdb modification? Looks like both methods to attach single protons need some kind of reference (control atoms).  Thanks much,

Marc
