Thank you for your interest in contributing to PeptideAtlas.
Please submit your proteomics DDA dataset to one of the ProteomeXchange Consortium repositories such as to PRIDE or MassIVE, with all of the mass spectrometer output files, either in their native format (e.g., .raw, .wiff, .d, etc.) or in mzML format. PeptideAtlas will pick it up from there for reprocessing.
If you have trouble or questions submitting your data, please contact us via our feedback form.
