[gmx-users] Re: amber force field in gromacs

[Alan]

Dear Leila,

Consider reading all about ACPYPI at acpypi.googlecode.com, specially the
wiki pages. Although you may not be interested in topology generation for
ligands, there's there important information about how to run amber force
fields in Gromacs environment.

And review carefully your ffamber installation. It looks I had some similar
issues in the past and although I never figured out what was the cause, a
simply careful reinstallation of ffamber solved the problem.

And if using amber force field, consider registering yourself at amber
mailing list (ambermd.org). I am suggesting that because as far as I know
from literature amber99sb is the most advanced force field from amber, yet
the year, but read:

Hornak, V., Abel, R., Okur, A., Strockbine, B., Roitberg, A., and
Simmerling, C. Compar- ison of multiple amber force fields and development
of improved protein backbone parameters. Proteins- Structure Function and
Bioinformatics 65, 3 (NOV 15 2006), 712–725.


However, I understand you want to do nucleic acids simulation rather than
proteins, so milage here is low and for that I suggested also the amber
mailing list.

I hope it may helps.

Alan
