Replicate our numerical results or reconstruct a force field from your own dataset with a Python implementation of sGDML.
Get started
The sgdml package uses a proprietary dataset format, but it is easy to convert from and to Extended XYZ files and other popular file formats (learn more):
$ sgdml_dataset_via_ase.py <xyz_dataset_file>A force field is created via a single command-line call that yields a ready-to-use model file:
$ sgdml all <sgdml_dataset_file> <n_train> <n_validate> [<n_test>]The last three parameters specify the sizes for the training, validation and test dataset splits, which are sampled from the provided dataset file without overlap. Leave out <n_test> to use all remaining points for testing (learn more).
A force field model is effectively a parametrization of your dataset that provides energy e and forces f for any input geometry r (learn more):
import numpy as np
from sgdml.predict import GDMLPredict
from sgdml.utils import io
model = np.load('model.npz')
gdml = GDMLPredict(model)
r,_ = io.read_xyz('geometry.xyz')
e,f = gdml.predict(r)This flexibility enables many applications, e.g. by interfacing to Atomic Simulation Environment (ASE). Here are a few examples:
