Get hands-on experience working with a data independent acquisition (DIA) parallel accumulation serial fragmentation (PASEF) data, from a Bruker timsTOF instrument, using a 3-organism mix data set created for instruction, based on the Navarro, Nature Biotech 2016 benchmarking paper. Use the Import Peptide Search wizard for DIA to build a spectral library from ddaPASEF data with automatic iRT calibration for retention time calibration and an mProphet learned model for peptide peak detection. Assess the data quality using a rich collection of Skyline summary plots including Retention Times, Peak Areas, Mass Accuracy, and CVs. Finally, perform a group comparison and make your own assessment of how well the data capture the expected ratios for each organism. (36 pages)
