OEMakeVoidVolume(mol1: Union[OEGraphMol,OEMol,OEQMol],
mol2: Union[OEGraphMol,OEMol,OEQMol],
grid: OEScalarGrid, resolution: float,
probeRad: float = 1.4) -> bool
Constructs a grid representing the void, or unoccupied, volume between a
ligand (mol1) and a macromolecule (mol2) that can accommodate a
spherical probe with radius less than probeRadius. The resolution of the grid
is specified by resolution. The grid grid is resized to fit a
5 Angstrom envelope around mol1, and its values are set to 1.0 inside
the void volume and 0.0 outside.
