Scope and considerations
Designed for
- FastEI combines learned spectrum embeddings with approximate nearest-neighbor indexing for EI library matching. It provides a Windows GUI and Python example workflows.
Not designed for
- General LC-ESI-MS/MS identification or raw chromatogram deconvolution.
Important requirements
- Compatible EI spectra plus the reference database, embedding model and index.
- Windows 64-bit for the packaged GUI, or the documented Python environment.
Considerations
- Predicted-library matches remain candidates; database coverage and spectral quality limit interpretation.
