To identify unknown compounds, compare mass spectra by matching your MGF file against a curated spectral library using similarity calculations. This process yields potential compound identifications complete with confidence scores.
For spectral analysis, you can import, filter, and standardize mass spectrometry data from mzML, MGF, and MSP formats. Standardizing these formats ensures consistent spectral comparison across different metabolomics data sources.
Available spectral similarity algorithms for metabolomics data processing include cosine, modified cosine, and fingerprint-based methods. These algorithms calculate similarity scores to robustly match spectra against reference libraries.
Yes, matchms works with mzML files, supporting spectral analysis for both proteomics and metabolomics research. It imports and processes mzML spectra to enable subsequent compound identification and spectral comparison.
The best way to filter and standardize mass spectrometry data before library matching is importing spectra from mzML, MGF, or MSP formats. Standardization aligns mass spectra, ensuring accurate similarity calculations during compound identification.
