I need to know what are the functions and properties of "atom object" do in chemira. I searched but I could not find!

Hi Elnaz, In IDLE you can type "dir(chimera.Atom)" to see the names of all methods/attrs of Atom, or "help(chimera.Atom)" to get a longer but somewhat more readable listing. We do have some information in the Chimera Programmer's Guide: Chimera Programmer's Guide but an encyclopedic listing of Atom attrs/methods isn't part of it. If you said what you were looking to accomplish I could probably offer better advice. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu
