The Trans-Proteomic Pipeline provides a complete workflow to generate spectral libraries suitable for OpenSWATH. Data sets acquired in data-dependent acquisition (DDA) or data-independent acquisition (DIA; preprocessed by DIA-Umpire ) can be searched by spectrum-centric scoring against a reference FASTA database using several supported search engines. After statistical validation using PeptideProphet, iProphet & MAYU, a consensus spectral library is generated by SpectraST, which serves as final input for the OpenMS tool

A comprehensive tutorial  describes the individual steps to generate spectral libraries for SWATH-MS using the Trans-Proteomic Pipeline (TPP). Please follow the tutorial until the generation of SpectraST spectral libraries. If you are using DIA data, follow the DIA-Umpire tutorial to generate pseudo-spectra first, which can then be processed using the TPP.
In the last step, import the SpectraST consensus library (format
splib) and convert it to a
MRM transition list:
# This will generate the file db_assays.mrm spectrast -cNdb_pqp -cICID-QTOF -cM db_consensus.splib
Convert then the
MRM transition list to a TraML spectral library and follow the remaining steps in the Generic Transition Lists section.
