[gmx-users] Re: converting proper dihedrals into ryckaert-bellemans

[Alan]

Dear Carla,

Let me suggest you the wikis at acpypi.googlecode.com.

And then let me ask why amber94 and not amber99sb? And why not trying
acpypi in the link above as I guess it can do pretty much what you
want with much less pain?

Cheers,
Alan
