FragPipe is a comprehensive computational platform designed for the analysis of mass spectrometry-based proteomics data. It includes a Graphical User Interface and pipeline wrapper code (FragPipe-GUI), distributed alongside various independent software tools and workflow files. FragPipe can be run using GUI or in the command line mode, on Windows, Linux, or in the cloud environment. It is powered by MSFragger - an ultrafast proteomic search engine suitable for both conventional and “open” (wide precursor mass tolerance) peptide identification. FragPipe includes Percolator and the Philosopher toolkit for downstream post-processing of MSFragger search results (PeptideProphet, iProphet, ProteinProphet), FDR filtering, and multi-experiment summary report generation. FragPipe includes MSBooster module for deep-learning based rescoring of peptide identifications. Crystal-C and PTM-Shepherd are included to aid interpretation of results from “open” and “mass offset” searches for post-translational modifications (PTM). FragPipe supports all modes of quantification, including MS1-based isotope labeling (e.g. SILAC) or MS1-based label-free quantification with FDR-controlled match-between-run (LFQ-MBR) using IonQuant IonQuant, TMT/iTRAQ isobaric labeling-based quantification using IonQuant and TMT-Integrator. FragPipe provides a comprehensive list of workflows for the analysis of data independent acquisition (DIA) data with MSFragger-DIA, DIA-Umpire/MSFragger, and diaTracer/MSFragger workflows for direct (“library-free”) peptide identification from DIA files, spectral library building with EasyPQP, and extraction of quantification using DIA-NN and Skyline.

Resources
The table below shows the compatibility of FragPipe workflow components with different spectral file formats.
Bruker .d indicates ddaPASEF files from timsTOF, other Bruker .d files should be converted to .mzML. Please also note that timsTOF data requires Visual C++ Redistributable for Visual Studio 2017 in Windows. If you see an error saying cannot find Bruker native library, please try to install the Visual C++ redistibutable.

DIA data acquired with overlapping/staggered windows must be converted to mzML with demultiplexing.
Quantification from Thermo .raw files with DIA-NN requires installation of Thermo MS File Reader, see the DIA-NN documentation for details.
