Dataset to support improved peptide and protein database search scores in chimeric MS/MS spectra

This dataset contains raw and processed data for liquid atmospheric-pressure matrix-assisted laser desorption/ionisation (LAP-MALDI) mass spectrometry analysis of mixtures of peptides and proteins using a modified Synapt G2-Si with an in-house built atmospheric pressure MALDI source. Chimeric MS/MS peak lists and filtered peak lists produced through the presented data acquisition/analysis workflow were searched using MASCOT.
