Workflow EBI NCBI BLAST filter e-value and length (1)

Thumb
The workflow queries the NCBI BLAST web service and extracts the e-values and length of the results. One of the sub-workflows filters the length first and afterwards the e-value and the other sub-workflow filters first the e-value and then the length. As the result may be different, this workflow was used for optimization purposes to find the sub-workflow performing best.

Workflow Biomarker Identification via EFS on the Grid (2)

Thumb
The first two components split the original data set into several sub-sampling sets. The EFS component performs the machine learning approach by executing several instances of a SVM, each of which consuming one sub-sample data set. Another level of SVM execution is added by taking bootstapping into account. The execution of all SVMs takes place in a distributed computing environment using the UNICORE-Taverna plugin. The calc_objFunc component calculates the F-measure of the ranked gene list ...

Workflow Biomarker Identification via RFE on the Grid (2)

Thumb
The first two components split the original data set into several sub-sampling sets. The RFE component performs the machine learning approach by executing several instances of a SVM, each of which consuming one sub-sample data set. The execution of the SVM takes place in a distributed computing environment, using the UNICORE-Taverna Plugin. The calc_objFunc component calculates the F-measure of the ranked gene list compared to a 'gold standard'.

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

Thumb
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 Optimization of retention time prediction (1)

Thumb
The workflow uses RTCalc from the TPP toolbox to perform two different retention time predictions. The third branch uses a linear retention time predictor (Palmblad et al., 2002). The workflow has a flag that switches on a specific branch.

Workflow ENM SVM workflow used for optimization (1)

Thumb
This workflow was used for the optimization of the SVM algorithm from the openModeller toolbox (http://openmodeller.sourceforge.net). The workflow uses 10-fold cross-validation and then calculates the average AUC, which can be used as fitness value during parameter optimization.
