[PyMOL] Mapping potentials in PyMOL

Hello All.

Having a electrostatic potentials map loaded in PyMOL
(an apbs map), does somebody know if there is a way to
get the potential associated with a given point in
space (i.e. to give a set of 3 spatial coordinates and
get the value for the potential at that point)?

Thanks in advance,

Raul
