What file formats does the Matchms skill support?

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

Does Matchms handle chemical structure data?

Yes, with the [chemistry] dependencies, it can derive InChI and SMILES codes, standardize chemical metadata, and calculate fingerprint-based similarities.

Can I use this skill to identify unknown chemical compounds?

Yes, Matchms allows you to calculate similarity scores between unknown query spectra and reference libraries using advanced algorithms like Modified Cosine.

Is Matchms optimized for large-scale data analysis?

Matchms is built for efficiency, offering fast similarity algorithms (like CosineGreedy) and batch processing capabilities suitable for high-throughput metabolomics.

How do I create a reproducible workflow with this skill?

You can use the SpectrumProcessor class to define a sequence of filters and processing steps that can be applied consistently across entire datasets.
