An acronym for Post Analysis Data Acquisition. PAnDA uses the Hardklor feature finder to define the molecular species in an LC-MS analysis and then uses this information to automatically construct new methods to specifically target features that were missed in subsequent analyses. PAnDA is particularly powerful when running technical and biological replicates to increase the fraction of the features that can be assigned a peptide identity.

Provides tools for analyzing shotgun proteomic data quantitated by spectral counting (with DTASelect) or labeling (with Census). The modules provide means to point differentialy expressed proteins / peptides (ACFold / TFold modules), find proteins with simmilar expression profiles in time-course experiments (TrendQuest module), find unique proteins to a state (Area proportional venn diagram module) and help interpreting results according to the Gene Ontology (Gene Ontology Explorer module). Minimum requirements: a computer with Windows XP SP2.

A semi-supervised machine learning approach for improving the analysis of tandem mass spectrometry data of peptides. Percolator uses a machine learning technique call a support vector machine to dynamically discriminate between correct and decoy spectrum identifications obtained by database searching. By using our approach, we are able to identify approximately 50% more peptides from a given μLC-MS/MS dataset.

The QCorr algorithm compares a tandem mass spectrum to a reversed copy of the same spectrum using a cross correlation.

RawExtractor is a program to extract MS and MS/MS spectra from RAW files generated by Thermo mass spectrometers, such as LTQ, LTQ-Orbitrap, LCQ, and stores the spectra in ms1, ms2 or mzXML file format. The spectra files generated by RawExtractor program are used as input for protein identification programs SEQUEST, ProLuCID and quantitatation program Census.

A method for performing protein identification & peptide sequencing by utilizing mass spectrometry fragmentation patterns to search protein and nucleotide databases has been developed by our lab. Our program, SEQUEST, converts the character-based representation of amino acid sequences in a protein database to fragmentation patterns which are compared against the MS/MS spectrum generated on the target peptide. The algorithm initially identifies amino acid sequences in the database that match the measured mass of the peptide, compares fragment ions against the MS/MS spectrum, and generates a preliminary score for each amino acid sequence. A cross correlation analysis is then performed on the top 500 preliminary scoring peptides by correlating theoretical, reconstructed spectra against the experimental spectrum. Output results are displayed accordingly.

Topograph is an advanced program for the analysis of proteomics data using stable isotope labeling. This software is still in the early stages of development. Improvements are added regularly.

YADA can deisotope and decharge high-resolution mass spectra from large peptide molecules, link the precursor monoisotopic peak information to the corresponding tandem mass spectrum, and account for different co-fragmenting ion species (multiplexed spectra). YADA also enables a pipeline consisting of ProLuCID and DTASelect for analyzing large-scale middle-down proteomics data.
