Hi, all, I have a pdb file only contains CA atoms. When I try to show cartoon about this protein, nothing happened. I found I can only show nb_sphere on the screen, is there a way to show cartoon based on those CA only pdb files? The secondary structures have been already defined in the pdb header.
