Hello List!

I have a pdb structure that is mostly alpha carbons except for a few
residues around a ligand. I would like to display the entire protein
with a CA tube and the active site in a more detailed representation.
However it seems that the residues that are only CAs are not recognized
as part of the "protein" keyword. When a pdb file is only CAs the
residues are recognized as protein. Is there any way to circumvent
this feature and draw a tube representation for all the CA atoms? Can
I adjust what is included in the "protein" keywords?
