1. Put the code below into a Python file (".py" file).
2. Run the file from within PyMOL ("run filename.py").
3. You can now use your new command as=20

mycba=20

or

mycba (atom selection)

You may want to put the code into $HOME/.pymolrc.py (unix) or =
$PYMOLPATH/pymolrc.py (windows) so that the new  command will always be =
available.

   s =3D str(selection)  =20
   cmd.color("magenta","("+s+")")
   cmd.color("oxygen","(elem O and "+s+")")
   cmd.color("nitrogen","(elem N and "+s+")")
   cmd.color("sulfur","(elem S and "+s+")")
   cmd.color("hydrogen","(elem H and "+s+")")
   cmd.color("pink","(elem C and "+s+")")

cmd.extend("mycba",mycba)
