I'm relatively new to pymol and been scratching my head over a problem I've had for a several days.  I would appreciate it if anyone could help.  I'm trying to show the coordinates of a selected atom.  Lets say you click on an atom and select it.  How do you then show its coordinates in 3D space.  Can you do this via pymol's interface or are the coordinates in the pdb file?
Thanks in advance for your help.
