Most-abundant isotopic peak precursor matching in MetaMorpheus: re-analysis results for the yeast top-down dataset MSV000081592

The top-down mass spectrometry data analyzed here were previously published by Schaffer et al.⁸ and are publicly available on MassIVE (https://massive.ucsd.edu) under accession MSV000081592. The complete re-analysis output of this study—per-fraction mzIdentML identification files for the monoisotopic baseline and most-abundant searches, proteoform- and PSM-level result tables, the MetaMorpheus parameter (TOML) files, the UniProt S. cerevisiae database used, and a README documenting the workflow
