Is Matchms suitable for high-throughput analysis?

Absolutely. Matchms is designed for efficiency, featuring fast algorithms like CosineGreedy and a SpectrumProcessor class for building batch-processing pipelines.

How does Matchms handle metadata standardization?

It includes over 40 filters that automatically harmonize compound names, correct charges, standardize adducts, and derive chemical structures like InChI and SMILES.

Can Matchms help with compound identification?

Yes, it facilitates compound identification by calculating spectral similarities between query spectra and reference libraries using metrics like CosineGreedy and ModifiedCosine.

Do I need extra dependencies for chemical structural analysis?

For processing molecular structures (SMILES, InChI, and fingerprints), you should ensure the chemistry-enabled version is used by installing 'matchms[chemistry]'.

What file formats does Matchms support?

Matchms supports a wide range of common mass spectrometry formats including mzML, mzXML, MGF, MSP, JSON (GNPS-compatible), and USI references.
