        I get the following error message when I use the
        command saveamberparmpert in leap:
        
        *** Proper torsion parameters missing ***
         atom names: ND1-CG-CB-HB2
         atom types: NB-CC-CT-HC =pert=> DNB-DCC-DCT-DHC
        Please add a dummy parameter of multiplicity 2
        for the pert types to your parameter set.
         - e.g. DNB-DCC-DCT-DHC 1 0.0 0. 2.
        
        I have added the missing parameters but I keep getting
        the same errors. Any ideas ?
        
Atom types should be 2 characters - this could be causing it.
Are you using pre-amber6 leap? I think v6 checks the length
of type names.
