Dear Chimera Support

I am a developer of consurf (http://consurf.tau.ac.il/) for displaying evolutionary conservation of amino/nucleic acid positions in a protein/DNA.

Till now we have been working with PDB files and inserting the coloring values in the b-factor (temperature) field in the ATOM part.

In the chimera script we use the color commands:

color CONS1 @/bfactor=1

color CONS3 @/bfactor=3

...

Now we wish to start using mmCIF files. Where should we insert the coloring values in the mmCIF file, and how do we reference then with the chimera commands ?

Best
