Hi Hajeung, To color all carbons green the command would simply be color green,a C whereas "byatom" means to use the built-in element coloring scheme, not a specific color <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/colortables.html#byelement> <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/color.html> and @ means atom name, not element, so "@C" would only get the atoms named C (not CA,CB, etc.). General user questions should probably go to chimera-users@cgl.ucsf.edu (chimera-dev is for development/programming questions). I hope this helps, Elaine ---------- Elaine C.
