[Chimera-users] coloring mmCIF files

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 CONS2 @/bfactor=2 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 Josef
