Hi Chimera fans,

Can someone please help me understand how to read and look at .nrg files 
(generated by Grid)?  I am interested in visually exploring the 
electrostatic potential around a protein.  Specifically, when I opened 
it, everything was in one color, with negatively charged regions being 
darker, but I would imagine that positively charged regions should have 
a different color.  On a related note - is there a tool to calculate and 
view the electric field lines around a molecule / protein?

Thanks for your time and help,
