OEMakeETGrid
OEMakeETGrid(grid: OEScalarGrid, mol: Union[OEGraphMol,OEMol,OEQMol],
et: OEET) -> bool
Calculates the electrostatic Tanimoto grid for the mol
passed in and the reference molecule that needs to be already set
to the OEET instance.
Both mol and the reference molecule set via
OEET.SetRefMol must have 3D coordinates and
partial charges assigned.
