'TOPP - The OpenMS Proteomics Pipeline' is a pipeline for the analysis of HPLC-MS data. It consists of several small applications that can be chained to create analysis pipelines tailored for a specific problem.
The TOPP tools are divided into several subgroups:
Graphical Tools
- TOPPView - A viewer for mass spectrometry data.
- TOPPAS - An assistant for GUI-driven TOPP workflow design.
- INIFileEditor - An editor for OpenMS configuration files.
- SwathWizard - A user-friendly step-by-step wizard for SWATH data analysis
File Handling
- DTAExtractor - Extracts spectra of an MS run file to several files in DTA format.
- FileConverter - Converts between different MS file formats.
- FileFilter - Extracts or manipulates portions of data from peak, feature or consensus feature files.
- FileInfo - Shows basic information about the file, such as data ranges and file type.
- FileMerger - Merges several MS files into one file.
- IDMerger - Merges several protein/peptide identification files into one file.
- IDRipper - Splits protein/peptide identifications according their file-origin.
- IDFileConverter - Converts identification engine file formats.
- MapStatistics - Extract extended statistics on the features of a map for quality control.
- TargetedFileConverter - Converts targeted files (such as tsv or TraML files).
- TextExporter - Exports various XML formats to a text file.
- MzTabExporter - Exports various XML formats to an mzTab file.
