Hey Eric,

actually I am using a backbone subset defined by Gromacs during the computing. Are you talking about backbone or main-chain sub-space?

I am using the latest version of ChimeraX but also I do have a ChimeraX daily installed on the same machine..

Cheers,

Enrico

Hi Enrico,
        Do you have all the backbone atoms, including the backbone oxygen?  What version of ChimeraX are you using?

When I load this multi-pdb ensemble to Chimera-X I can see only back-bone traces without any secondary structure information. I've tried to use dssp command to re-assign the secondary structure but it did not change the visualization state. Would it be possible to do it in some automatic fashion via some built-in command?
