[Chimera-users] commands to add red spheres to the ribbon structure

Hi Bin,
As far as I know, the same commands as in earlier versions should work.  However, the trick (same as before) is to use the “ribbackbone” command to allow showing backbone atoms at the same time as ribbon.  Then you can show the alpha-carbon as a red ball.  For example, commands:

open 1hd2
ribbackbone
# hide atoms
~disp
disp :57 at ca
repr sphere :57 at ca
color red,a :57 at ca

In the last command, “,a” means atoms-only (not ribbon etc.).  I hope this helps,
Elaine
