Scope and considerations

Designed for

  • MASSISTANT provides research code for learning molecular SELFIES representations from electron-ionization mass spectra.

Not designed for

  • Immediate inference with a distributed final model; the README still marks prediction instructions and a Docker image as forthcoming.

Important requirements

  • A compatible research environment and appropriately licensed EI training spectra; the repository does not supply the commercial-NIST-trained models.

Considerations

  • This is a training-oriented research release. Valid SELFIES syntax does not establish that a predicted molecule is the experimentally measured compound.

Access and documentation

Public research source, no repository-wide license grant established, and final NIST-trained models are not supplied. Users must obtain suitable data rights and train their own model.
