[Chimera-users] simple question

[Elaine Meng]

Hi Arthur,
If you are showing ribbon, it suppresses the display of backbone atoms.  To enable showing both backbone atoms and ribbon at the same time for the same residue, you would need to use command “ribbackbone”.   (Then you may still need to display the atoms after that.)  Alternatively you can hide the ribbon for just that residue (e.g. select it and then use Actions…Ribbon… hide) and then show whatever of its atoms that you want.  However, it will then be detached from the rest of the ribbon and look like it is floating.  Yet another approach is to not use any ribbons for that figure.
I hope this helps,
Elaine
