ProteoWizard is a modular and extensible set of open-source, cross-platform tools and software libraries for proteomics data analysis.
The libraries enable rapid tool creation by providing a robust, pluggable development framework that simplifies and unifies data file access, and performs standard chemistry and LCMS dataset computations.
The software is available for download now.
Core code and libraries are under the Apache open source license;
the vendor libraries fall under various vendor-specific licenses.
