NAME

topp - library for LC/MS data management and analysis - tools
 

DESCRIPTION

This manual page documents briefly the topp package that brings a set of binary tools to build the OpenMS proteomics pipeline (topp). OpenMS offers an infrastructure for the development of mass spectrometry-related software and powerful 2D and 3D visualization solutions. OpenMS offers analyses for various quantitation protocols, including label-free quantitation, SILAC, iTRAQ, SRM, SWATH… It provides build-in algorithms for de-novo identification and database search, as well as adapters to other state-of-the art tools like X!Tandem, Mascot, OMSSA… OpenMS supports the Proteomics Standard Initiative (PSI) formats for MS data and supports easy integration of tools into workflow engines like Knime, Galaxy, WS-Pgrade, and TOPPAS via the TOPPtools concept and a unified parameter handling.
