stko.MMFFEnergy

class stko.MMFFEnergy(ignore_inter_interactions=True)[source]

Bases: object

Uses the MMFF force field to calculate energies.

Examples

import stk
import stko


# Create a molecule whose energy we want to know.
mol1 = stk.BuildingBlock('CCCNCCCN')

# Create the energy calculator.
mmff = stko.MMFFEnergy()

# Calculate the energy.
results = mmff.get_results(mol1)
energy = results.get_energy()
unit_string = results.get_unit_string()
