Scope and considerations

Designed for

  • GNN-RT learns molecular-graph representations for retention-time prediction, with training and transfer-learning scripts for applying the model to a chromatographic dataset.

Not designed for

  • Direct peak detection, structure confirmation or method-independent retention-time prediction.

Important requirements

  • Python, PyTorch, RDKit and data prepared for the provided scripts.
  • Training or transfer-learning data appropriate to the chromatographic method.

Considerations

  • Predictions depend on chemical and chromatographic applicability; use them as supporting annotation evidence.
