Dear all,

My peptide contains many non-standard residues like Aib and D-isovaline.
How can I represent them in Ribbon or cartoon conformation. Otherwise the
peptide looks broken.

The error is :
Warning: ribbons code encountered an unusual structure, geometry may not
look as expected

Any ideas?

Best wishes
