Workflow X!Tandem and PeptideProphet on the Grid (1)

The workflow performs the execution of X!Tandem and PeptideProphet from the TPP toolbox on the Grid. The execution is performed by the UNICORE Plugin for Taverna. mzXMLDecomposer/Composer is used to run the execution of X!Tandem in parallel. extract_values extract relevant information from thetandem.interact.pep.xml File. The file can then remain on the remote storage.

Workflow ROC_AUC_Workflow (1)

This small workflow extracts the area under the curve (AUC) from the receiver operating characteristic (ROC) curve for all charge states analyzed by PeptideProphet. This measure can be used to compare the sensitivity and specificity of different search engines for matching tandem mass spectra to peptides.
