Affimetrix microarray: part two (perm) (1)

• Download

We use a permutation test to infer the significance of the differently expressed genes found by the ANOVA analysis. Permutation tests are computationally intensive, needing at least 1000 permutations per gene to obtain acceptable results. For large experiments, the in-built feature of running R/MAANOVA in a single cluster may not be enough. We are using WS- VLAM workflow management system [2] to create a Grid-enabled R/MAANOVA workflow (Grid-MAANOVA) that will simultaneously run in multiple c...

Basic eSearch/eFetch cycle (1)

• Download

This is a basic eSearch/eFetch workflow created with taverna and using eUtils from NCBI. It accepts a query term as input (at the moment, for testing purposes, this is a fixed string), interrogate eSearch to retrieve the list of related sequences on the Nucleotide database, and use eFetch to retrieve the corresponding sequences. I wrote this workflow one year ago, when I was trying to understand how taverna and eUtils work; I suspect it broken, and of course it could be enhanced, so I am ...

AUGUSTUS Workflow for predicting genes in ... (1)

• Download

AUGUSTUS is a program that predicts genes in eukaryotic genomic sequences. Currently, it has been trained to predict genes in human, Drosophila melagonaster, Arabidopsis thaliana, Brugia malayi, Aedes aegypti, Coprinus cinereus, Tribolium castaneum, Schistosoma mansoni, Tetrahymena thermophila, Galdieria sulphuraria and Zea mays. In addition the species parameters of the following species are a courtesy of Jason Stajich: Caenorhabditis elegans, Saccharomyces cerevisiae, Ustilago ma...

Make 28 CPUh load on the Grid (1)

• Download

This workflow makes 28 CPU hours load on a Grid. Therefore it calls 100 times (represented by 100 input tokens) the program "makeload", which makes 1000 Seconds load each. The processing is done recurrent, so you can use this workflow to benchmark the speedup of your Grid environment, or just to heat up your computer center... This workflow also serves as an example of a typical parameter study modeled with GWorkflowDL. Of cause this workflow can only be invoked with a X509 certif...

GWorkflowDL: Generic execution of programs (1)

• Download

This workflow is an example of the execution of an arbitrary command line program. This workflow transfers a tar.gz package containing the linux program "date" to a free Grid resource, unpacks, and executes it. After execution the URL to the file with the standard output is available on "stdout", the standard error on "stderr".

Calculation of molecular descriptors for m... (1)

• Download

This workflow loads iteratively molecules from a database. For each molecule the atom typse are perceived before the hydrogens are added and the aromaticity is detected. Than the QSAR worker calculates the selected descriptors. The result of this calculation is stored in database table.

Topological Substructure Search Workflow (1)

• Download

This workflow performs a topological substructure search. The molecules to be searched are loaded from a MDL SD file. The substructure is loaded from a SMILES (workflow input). The matched molecules are converted to CML and for the molecules which do not contain the substructure the InChI is generated.

While Sample (1)

• Download

This WF shows how to use while constructs in workflows. The condition block generates a true or false condition. The while loop is executed once, each time the condition is true.
