Software

pFind

    pFind is a search engine for peptide and protein identification via tandem mass spectrometry.  [more...]

pXtract

    pXtract creates .DTA .MGF and .MS2 input files directly from Thermo Scientific .raw LC-MS/MS data files.  [more...]

pScan

    pScan is a flexible tool that helps biologists to preprocess protein sequence databases in proteomics research.  [more...]

pBuild

    pBuild is a tool that can compare several search engines' results and combine them together. The latest version, pBuild v2.0, can process the search results of pFind, SEQUEST and Mascot.  [more...]

pLabel

    pLabel is a spectra labeling tool that can visualize the global- and local-view peptide-spectrum matches, given the results of pFind or any other search engines. pLabel can label both CID and ETD spectra, and implement the manual de novo sequencing.  [more...]

pCluster

    pCluster is a software tool aiming at detecting protein modifications independent of sequence databases by tandem mass spectral clustering.

pQuant

    pQuant provides full MS scan based isotope labeling quantification strategy.  [more...]

pLink

    pLink is a software dedicated for the analysis of chemically cross-linked proteins or protein complexes using mass spectrometry.  [more...]
