You have been very helpful in explaining different items that use the
I have a PDB file that was determined by NMR. Thus there are a large number
of chains number as pdb (#0.1) Chain A etc.
So I know that I can select a single chain, and build up an image with
Chains A, B, etc using the #0.1 chain number.
I want to visualize three Gly residues in one chain. So I learned that I can
use the command ribbackbone to visualize the backbone atoms of the amino
acids that I want to show. So when I use that command all the backbone
atoms of the residues selected are visualized including the side chains. I
also know that if I use the command ~ribbackbone all the backbone atoms are
suppressed leaving only the atoms of the side chains. I know that without
any residues or atoms specified the command applies to the whole model.
Now as I said that I want to visualize three Gly residues in one of the
chains. The Gly residue numbers are 33, 37, 38. They are on Chain #0.1 K.
The information on the ribbackbone in the Chimera users guide, indicates
that I should be able to do this by using parameters termed atom-spec.
i.e. ribbackbone atom-spec <frameatom_spec.html>
I looked elsewhere for how to designate the parameters for atom-spec and
tried a few things, but I was not able to achieve the specificity of showing
the backbone atoms of only the Gly residues. I don't think that I have to
indicate that I want only the Gly residues in Chain K #0.1 because I can
select the Gly residues from the sequence of Chain K #0.1.
So after this long description of what I want to do, would you kindly inform
me of how I can visualize the backbone atoms of only Gly.
