Help with capping of helices - ribbon style
Hello, Recently I downloaded the new version of ChimeraX and noticed that in the ribbon style the helices now look hollow. In the older version of chimera, the helices were capped. Is there a way to cap the helices in the new version? Below is an example from the old version and the new version: Old: [cid:1fff36fe-586e-4307-98f3-a2f03b125fde] New: [cid:86e871a6-1c71-4488-9bc3-f1b209a57bec] Thank you for your help. Best, Eliane
Hello Eliane, Sorry no, I can't think of any way to cap the ribbons so that they look solid instead of hollow. However, I believe this is the same in Chimera and ChimeraX. Looking at both programs right now, when I slice the ribbon it appears hollow. Best, Elaine ----- Elaine C.

Elaine is right that both ChimeraX and old Chimera have hollow ribbons and if you clip them you see inside. Your first image looks like a tube (ChimeraX command "shape tube #1@CA" which is not an actual ribbon but just a tube surface. Hollow surfaces are capped. Tom
