MSQuant is a tool for quantitative proteomics/mass spectrometry and processes spectra and LC runs to find quantitative information about proteins and peptides. Though automated it also allows manual inspection and change.

MSQuant's main purpose is to make quantitation of proteins and peptides possible in the area of mass spectrometry/proteomics (science/analytical chemistry/molecular biology). E.g. an experiment where one heavy isotope-labeled sample from treated cells is compared to unlabelled, untreated cells to give quantitative answers about cellular processes. The input to MSQuant is a search result file (HTML) from the Mascot search engine (from Matrix Science).

MSQuant is written in Microsoft's .NET and thus can only run on Windows computers that have the .NET runtime installed. The runtime is installed by default in later versions of Windows.

MSQuant is released at SourceForge

You can validate your peptide identifications from the raw data (QSTAR shown here).
