Which software do you have in mind for generating an ESP cube?
For consistency I'd like to stick as closely as possible to the methods
that other folks have used in the past, for example in the original RESP
papers. It seems the standard is to use points from four Connoly surfaces,
at 1.4, 1.6, 1.8 and 2.0A from the vdw surface of the atoms.
Fitting a cube of regularly sampled points is possible, in principle
(especially if there is some kind of distance-from-atom dependent weighting
to the points), but it seems it would not be exactly the same as Connoly
surfaces, and I'm not sure antechamber can use a cube as an input.
Best,
Alex
