Hi,
If you are doing an MD in amber7 you can make a force field modification file including
the missing parameters. You could try to get these parameters from a variety of
different sources. The best of course would be to run the ab initio calculations to
get these values. As a less expensive solution you could try to get the parameters
from gaff (in Amber 7) or from a molecular mechanics program such a macromodel that is
well parametrized. Hope this helps.
Cheers,
Joey
