Philosopher is a fast, easy-to-use, scalable, and versatile data analysis software for mass spectrometry-based proteomics. It is also a depencency-free wraper of Trans-Proteomic Pipeline (PeptideProphet, iProphet, PTMProphet, and ProteinProphet).

• Database downloading and formatting.

• Peptide assignment validation with PeptideProphet.

• Multi-level integrative analysis with iProphet.

• PTM site localization with PTMProphet.

• Protein inference with ProteinProphet.

• FDR filtering with custom algorithms.

• Two-dimensional filtering for simultaneous control of PSM and Protein FDR levels.

• Sequential FDR estimation for large data sets using filtered PSM and proteins lists.

• Label-free quantification via spectral counting and MS1 intensities.

• Label-based quantification using TMT and iTRAQ.

• Multi-level detailed reports for peptides, ions, and proteins.

• Support for REPRINT and MSstats.
