Note

This release updates espaloma to support the newest version (1.1.2) of DGL. There are no API breaking changes or updates to the espaloma model. We have attached espaloma-0.3.2.pt to this release for convince, but this model is identical to espaloma-0.3.1.pt. espaloma-latest.pt is also the same as espaloma-0.3.1.pt. Please see https://github.com/choderalab/espaloma/releases/tag/0.3.1 for more information about the espaloma 0.3.x family of models.

Full Changelog: 0.3.0...0.3.1

Model updates

• Note that espaloma-0.3.0.pt is also deployed which is compatible with espaloma-0.3.1.pt. espaloma-0.3.0.pt was renamed to espaloma-0.3.1.ptto maintain consistency with the release version.
• espaloma-0.3.1.pt (espaloma-0.3.0.pt) is a new espaloma model (see notes_for_espaloma-0.3.1.pdf for more details) with the improved features:
  • Trained with curated quantum chemical dataset covering small molecules, peptides, and nucleic acids, containing over 15,000 unique molecules and 1M conformations
  • Improved training strategy that uses both energies and forces, as well as L2 regularization to proper and improper torsion force constants to reduce the model complexity and variance
  • Restrict improper torsion multiplicity to n=1,2

Notes

• espaloma-0.3.1.pt (espaloma-0.3.0.pt) was trained and created using a dev version (commit: 4c6155b) of v0.3.1 release based on openff-toolkit 0.10.6
• A manuscript describing the complete fitting process and assessment is forthcoming
• Please warn that v0.3.0 is no longer compatible with v0.3.1, and espaloma-0.3.1.pt is not supported by v0.3.0

What's Changed

• Get rid of large storage by @yuanqing-wang in #133
• Fix nonbonded force subtraction by @kntkb in #134, #140
• Exclude resonance variant input features by @yuanqing-wang in #148

Full Changelog: 0.2.4...0.3.0

Model Update

• espaloma_0.3.0rc1.pt is deployed as a release candidate for espaloma_0.3.0 (see notes_for_espaloma-0.3.0rc1.pdf for more details).
• Please note that notes_for_espaloma-0.3.0rc1.pdf are temporal and manuscript describing the complete fitting process and assessment is forthcoming.
• Please warn that espaloma_0.3.0 is no longer compatible with the 0.2.x models, and vice versa.

New Contributors

• @jthorton made their first contribution in #122
• @kntkb made their first contribution in #124

Full Changelog: 0.2.3...0.2.4

Fixed the index casting bug caught by new version of DGL.

Used Smirnoff-style 3-termed improper torsion in stead of 6-termed. (#105)

This version is concurrent with: https://arxiv.org/abs/2010.01196v3

Erased global DGL import to make package compatible with Conda-forge.

Code base for https://arxiv.org/abs/2010.01196 v2.

This release is responsible for generating the results for https://arxiv.org/abs/2010.01196.
