That looks helpful. Thanks. >So if it finds a bonded interaction that involves an atom type >it doesn't know about (e.g. you have a type in ffbonded.itp but not >ffnonbonded.itp, which I bet is the case here) you get a fatal error. Got it! It's a little more subtle that that though. forcefield.itp has >#include "ffcgenbonded.itp" >#include "ffcgennonbonded.itp" so it's loading the bonded parameters before the non-bonded, it needs to be the other way around. I'd never have worked that out on my own. Now to fix the next error. Thanks for the help!
