I posed this question some while back and thought I'd submit it again as my question wasn't answered completely. 

Is it possible to have APBS spit out a list of values for points on the surface? I'd like to be able to quantitatively compare surface electrostatics of volumetrically identical proteins. I've been able to export a mesh of points on the solvent accessible surface but would also like to have electrostatic potential values at those points.

Thanks!
