I don't think so, although they should be highly correlated if the model is well fit to the density. 

The Q-score as I understand it is more akin to a per-atom correlation of a map simulated from the atomic model with the experimental density map, whereas just sampling the local resolution at atom positions does not depend the model in the same way.

Isn't this what Q-scores does?

Hi Yiannis,

I am not sure whether this is possible in ChimeraX yet, but you can do this in Chimera using a combination of `Values at Atom Positions` and `Render by Attribute`.



Cheers

Dear all,

I am trying to color a protein model based on the local resolution of the corresponding map. I can color the overall surface of the model, but not the residues themselves. Is there a way to do this, e.g, color the model backbone somehow?

Thanks a lot for your help!

Cheers,
Yiannis
