Scope and considerations

Designed for

  • FIDDLE predicts and rescores molecular-formula candidates from tandem mass spectra using deep learning.

Not designed for

  • Full molecular-structure identification or guaranteed formula recovery outside the supported instrument and chemical domains.

Important requirements

  • The inference package and downloaded models, plus MGF spectra containing the required title, precursor mass/type and collision-energy metadata; select the appropriate instrument model.

Considerations

  • Formula ranking and rescoring depend on spectral metadata and model selection. Optional BUDDY/SIRIUS comparisons add separate software and account requirements.
