All of the atom names from the residue in FAD.pdb _must_ match the atom
names used for the same atoms in the OFF files you downloaded.

That's how leap is able to determine the appropriate atom types. You
will need to modify all of the atom names in the FAD residue in your PDB
file to match those stored in the OFF files.
