Hi,

I don't see why it doesn't all work, can you not just use the ffoplsaanb.itp file to map the opls_xxx names to the ones used in ffoplsbon.itp?

Cheers

Tom

Hi All,

I am trying to build the itp file for a molecule. I would like to use
the opls force field. The ffoplsaa.atp contains the atom types as
opls_xxx. But the ffoplsbon.itp which contains the bond-angle-dihedral
parameters does not use the opls_xxx convention. Is there a way to
identify the bond/angle/torsion parameters of a set of opls_xxx atoms?

There ought to be a mapping somewhere... ffoplsaanb.itp has opls_xxx and
then some other stuff, but it doesn't all work... weird.
