-- `psmconvert` - The convert_psm function converts peptide spectrum matches (PSMs) from an idXML file to a CSV file, optionally filtering out decoy matches. It extracts and processes data from both the idXML and an associated spectra file, handling multiple search engines and scoring systems.
-- `mzmlstats` - The `mzmlstats` processes mass spectrometry data files in either `.mzML` or `Bruker .d` formats to extract and compile statistics about the spectra. It supports generating detailed or ID-only CSV files based on the spectra data.
