OETautomersLargestZoneSize

OETautomersLargestZoneSize(mol: Union[OEGraphMol,OEMol,OEQMol],
                           tautomerOptions: OETautomerOptions) -> int
OETautomersLargestZoneSize(inmol: Union[OEGraphMol,OEMol,OEQMol],
                           maxZone: int = 0) -> int

This function returns the largest number of atoms in a continuous tautomerization zone for the molecule and OETautomerOptions instance passed in as arguments. The later function provides a convenient function that relies on the default tautomer options other than potentially the maxZone size. The return value of this function plays a significant role in determining the upper bounds of the runtime for tautomer calculations on the molecule.
