[Chimera-users] display ribbon for CA atoms

[Bala subramanian]

Friends,
I am trying to visualize a helical structure containing only the CA atoms.
Chimera doesnt display ribbon for some of atoms, a reason which i dnt
understand.

I have tried to visualize in several versions 1.10, 1.9, 1.7 etc. I am
pasting the coordinates below of my pdb. You insights would be of great
help to resolve the problem.
