Re: FAD parameter and topology files

Hi Amit,
The tricky part here is the flavin, as the rest of the molecule can be
pieced together from existing components in the charmm force field. If
you're in a rush you could use our published FMN parameters (see!divAbstract).
However, at present I'm working on a newly revised FMN parameter set which
I suspect will be much better than the one we used a couple years ago. I'm
hoping it will be done in the next month or so, and I'd be happy to share
it once it is ready for production.
