[Chimera-users] select by color (or other display attributes)

[Oliver Clarke]

Hi, one feature I would love to see in a future version of chimera is the capacity to select residues/atoms by color - this would be magic for modifying figures.

Example use case: I’ve made a figure in which some complicated selection or set of selections is colored medium blue, and another selection is colored red. I’ve saved the session for the figure, but I (stupidly)didn’t save the corresponding selections, and now I have to remember exactly what selections I used. If there was a “select by color” function, I could simply select all the atoms that are colored medium blue (or some other color ID), and change them to another color, without having to know which residues were in the original selection. 

Analagously, it would also be handy, although less frequently useful, to be able to select on the basis of whether a residue is displayed, or represented in a particular manner - in particular, being able to restrict selection to displayed atoms/residues would be useful to avoid inadvertent modification of undisplayed models or parts thereof.

Cheers,
Oliver.
