The file itself is tab-separated without header, contains a single line per mzML file specified as follows:
`/path/to/file instrument_type sample_or_sampleset_name OPTIONAL:fractionation_plate_name OPTIONAL:fraction_nr`
Fractionation is automatically detected from this file, and enforced if ANY of the files have a fraction. This mainly has implications for QC though, identification and quantification are not much impacted by specifying fractionation. Instrument type can currently be one of 'qe', 'qehf', 'velos', 'lumos', 'qehfx', 'timstof', or 'lowres'.

### Output types
The pipeline will produce by default PSM, peptide, and protein tables. You may pass FASTA databases that contain mixtures of ENSEMBL, Uniprot, or other types of entries. Use `--genes` and `--ensg` to output a gene(name)-centric table and an ENSG-centric table. If you rather have less output, use `--onlypeptides` to not output a protein table.
