The following examples are available in the OpenFF toolkit repository. Each can be run interactively in the browser with binder, without installing anything on your computer.
- toolkit_showcase - parameterize a protein-ligand system with an OpenFF force field, simulate the resulting system, and visualize the result in the notebook
- forcefield_modification - modify force field parameters and evaluate how system energy changes
- conformer_energies - compute conformer energies of one or more small molecules using a SMIRNOFF force field
- SMIRNOFF_simulation - simulation of a molecule in the gas phase with the SMIRNOFF force field format
- vsite_showcase - two examples of using SMIRNOFF force fields virtual sites - a ligand with virtual sites on sulfure and chlorine and a comparison between the SMIRNOFF and OpenMM implementations of TIP5P
- QCArchive_interface - retrieving data from the QCArchive into
Moleculeobjects - forcefield_modification - modify force field parameters and evaluate how system energy changes
- using_smirnoff_in_amber_or_gromacs - convert a System generated with the Open Force Field Toolkit, which can be simulated natively with OpenMM, into AMBER prmtop/inpcrd and GROMACS top/gro input files through the ParmEd library.
- swap_amber_parameters - take a prepared AMBER protein-ligand system (prmtop and crd) along with a structure file of the ligand, and replace ligand parameters with OpenFF parameters.
- inspect_assigned_parameters - check which parameters are used in which molecules and generate parameter usage statistics.
- using_smirnoff_with_amber_protein_forcefield - use SMIRNOFF parameters for small molecules in combination with more conventional force fields for proteins and other components of your system (using ParmEd to combine parameterized structures)
- visualization - shows how rich representation of
Moleculeobjects work in the context of Jupyter Notebooks.
