Hi,
So I was defining link information for backbone bonds, angles and dihedrals under the link directive as follows but this information do not show up in the molecule.itp file. Is this a bug or am I doing something wrong with the definitions:
;;;; Links

;; Links for COIL. We apply them first as coil is the default.

resname $na_resnames
[ bonds ]
