It would be great if you could provide a simple example of this problem.
This error is different than the much more common one where the atoms in
the library don't match the atoms in the input PDB file.

I agree that the antechamber procedure for generating modified amino acids
(using "capped" model compounds) can be very un-intuitive. This page may
help:

Alternatively, the R.E.D. site has a different approach, and Francois has been
very willing to help with particular problems.

...good luck...dac
