**What it does**

PyProphet: Semi-supervised learning and scoring of OpenSWATH results.

Export tabular (tsv) tables. 

Optional SWATH2stats output. SWATH2stats is intended to transform SWATH data from the OpenSWATH software into a format readable by other statistics packages while performing filtering, annotation and FDR estimation.

**Study desing file for SWATH2stats**

    - Tabular file with columns that are named: Filename, Condition, BioReplicate, Run. 
    - The Filename should be part or the same as the original filenames used in OpenSWATH workflow
    - The Condition should be a 
    - The BioReplicate is corresponds to the biological replicate
    - The Run is the number of the run in which the sample was measured

PyProphet is a Python re-implementation of the mProphet algorithm (Reiter 2010 Nature Methods) optimized for SWATH-MS data acquired by data-independent acquisition (DIA). The algorithm was originally published in (Telemann 2014 Bioinformatics) and has since been extended to support new data types and analysis modes (Rosenberger 2017, Nature biotechnology and Nature methods).
