[Chimera-users] How to

I believe this has been the same for many versions -- the default is to hide backbone atoms where ribbon is shown.  

However, you can show backbone atoms and ribbon at the same time after you use the command "ribbackbone."  Show the command line (under Favorites menu), then enter the command ribbackbone, then display whichever atoms you wish. 

It may not look very good when you are showing the backbone atoms and the ribbon for the same residue, because the atoms may be "floating" away from the ribbon.  The ribbon is a smoothed path and in some places it does not follow the atoms closely.  More discussion of this issue, in case you are interested:

I hope this helps,
