Hej,
you can try to exclude the backbone from your selections using "not":
select V27, (resi 27 and EXA) and not (name N+C+O)
# I included the CA in this selection
etc.
This should select the residue atoms excluding the backbone (except CA).
If you have hydrogens in the structure you may need to modify the selection
to also exclude certain hydrogens:
select V27, (resi 27 and EXA) and not ((name N+C+O) or ((neighbor (name
N+C+CA+O)) and elem H))
Now you should be able to color and display the object sequentially,
without overlap:
show_as cartoon, all # secondary structure
show sticks, V27 # shows the residue as sticks (including CA)
color green, all # base color
color red, V27 and not CA # colors the residue red (excluding the CA)
Hope this solves the issue.
Cheers,
Andreas
