[Chimera-users] Molecule Display

[Elaine Meng]

Hello,
My guess is that you are showing ribbons.  When you are showing ribbons, by default all the backbone atoms are hidden, and since glycine does not have a sidechain, that means all the atoms of glycine are hidden.

You can either hide ribbons and show the atoms, or if you want to show both ribbons and backbone atoms at the same time, enter this command:

ribbackbone

<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/ribbackbone.html>

Then you will still have to display whichever backbone atoms you want, if they weren’t already displayed (but hidden by ribbon).  However, because the ribbon path is smoothed, the backbone atoms may be separated in space from the ribbon.

This is explained in the manual, along with some possible ways to improve the display:

I hope this helps,
Elaine
