Thanks for the speedy response!

I have seen this page before and looked through it, however I've found it not very instructive in terms of syntax. Suggestions on other places to look?


Thanks again,

The page you want is probably this:

http://ambermd.org/formats.html

The "current" ff03 being used in Amber14 should be just that--ff03. There
are updates to that force field, but they have name extensions.
