Dear PyMol users!

As I've understood there are no posible ways to represent H-bonds in proteins in explicit manner. So I'm looking for possible way to do it via some plugin or another way.

In particular I need
1) to visualize H-bonds in some structural motifs like coiled coil wich are dimers of alpha helices  ( so I'd like to see H-bonds beetwen separate alpha helices )

2) to visualize H-bonds in spicified SS structure ( e.g during formation of the alpha helices)- so I'd like to see H-bonds beetwen amide and Carboxy groups in specified amino acid sequence.

3) Finally I'd like to check H-bond in protein-ligand complex ( beetwenn specified ligand groups as well as some amino acid residues of the ligand binding pocket)
