ChimeraX - Color by seq_conservation fails in tutorial

[Sean.Moore@…]

Hello,

I am learning how to color by conservation and I am using the tutorial here:

https://www.rbvi.ucsf.edu/chimerax/data/conservation-coloring/conservation-coloring.html


In that guide, after opening 121P , hiding solvent, and ball-sticking the ligand, I then downloaded the alignment from within ChimerX using:

open https://www.rbvi.ucsf.edu/chimerax/data/conservation-coloring/121p-consurf.aln

That worked OK.

Then, the command :  color byattr seq_conservation  fails :

“No known/registered attribute seq_conservation”

I understand this feature was recently implemented in ChimeraX and I don’t know if it’s a known problem.

Is there a work-around?

Sean

Hi Sean,

What version of ChimeraX do you have? The version should be reported at the top of the log when you start up. Sequence conservation attributes were added in version 1.1, so if your version is earlier than that you will need to upgrade.

Thanks Eric.

The version is 0.91, that’s probably the issue!

I’ll update and check again later today.

Regards,

Sean
