The original raw data for proteomics datasets currently included in ProteomicsML.org have already been made publicly available through ProteomeXchange , mostly via the PRIDE Archive. Instead, the data hosted at ProteomicsML are provided in an ML-ready format, with links to original metadata and raw files for full provenance. Even though the datasets at ProteomicsML do not contain raw files, we do aim to provide users with extensive tutorials on how to process raw data into ML-ready formats.
