Hello, My name is Luis Cuello and I am a graduate student at the University of Virginia….I started using chimera recently but I have not been able to colored my files by B-factors values, Is there any way to do that with chimera software??? If you could help me in this matter I would appreciated….
Hi Luis, We intend to make a nice interface for coloring structures by associated numerical values (such as B factors), but for now a series of typed commands will do what you want to do. To color a structure so that B factors less than 10 are shown as green, between 10 and 20 as yellow, and over 20 as red, do: color green color yellow @/bfactor>10 color red @/bfactor>20 Obviously, use whatever numerical cutoffs and colors you want. There is a discussion of the the atom/residue/model attributes you can use in commands at http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/ atom_spec.html#descriptors .
