Example for external tools with gzip and g... (1)

• Download

This workflow is self-contained. It has a fixed URL from which a text file is downloaded (output as Original_file). That file is gzipped (output as Compressed_File) and then gunzipped again (output as Decompressed_File). The workflow wraps external tools from taverna.nordugrid.org and needs a beta version of Taverna 2.3 or later.

• Download

The workflow is an examples for the External Tools / UseCase plugin to integrate external tools. It wraps the "bc" command line calculator. Internally, it executes the following script: if [ ! -r "$1" ]; then echo "Cannot read file indicated by first argument '$1'." ; exit -1 ; fi ; if [ ! -r "$2" ];then echo "Cannot read file indicated by second argument '$1'." ; exit -1 ; fi if [ -x /usr/bin/bc ]; then ...

Retrieve details on genetic marker by UniS... (3)

• Download

The workflow retrieves the marker's primers and the organism name - if available. The organism name may not be unique for a given marker. The primers should be. It would be nice if some good soul could investigate how to retrieve the various mappings from the site. The retrieval of the primers is thought to prepare for a manual mapping of the marker's chromosomal location.

• Download

When retrieving a URL or soemthing alike, one can often identify the region of interest as a single line. Besides the expected output, also some interim values, like the lines split are forwarded, to allow some straight-forward cascading of filters with reduced redundancy.

dbfetch tutorial (1)

• Download

This workflow eases entry in the world of Taverna with one of the key tasks - the retrieval of plain data. The dbfetch offers sequence and structure data from a large variety of sources. A first execution of this workflow informs about these in the "getSupportedDBs" output. Also the formats and styles are listed. The two inputs allow for the specification of a query that leaves the format with "default" (which is different for every database, "native" would be a better fit), the style is alw...

The workflow tests the standard-compliance of web service descriptions of ARC-1, a development of the EU project "KnowARC" to modernise the grid infrastructure ARC of the NorduGrid. Learn more about it on http://www.knowarc.eu and http://www.nordugrid.org. If you have computers in spare - join us - and help you very own and many other sciences. And you make many interesting contacts just en passent. No authorisation is required for this very experimental service.

Structural alignment of arbitrary number o... (1)

• Download

This grid-executed Mustang application performs a structural alignment of protein sequences. The number of arguments is variable, in principle, but is shown here for three. The application is executed via the Taverna-ARC plugin on a machine of the NorduGrid. Although your machine can be a part of it, you may prefer to wait for a later version of that interface that does not require grid certificates.

• Download

The ZINC database (http;//zinc.docking.org) is a collection of substances with known structures and some chemical characterisation that are commercially available. It is freely available and a much respected resource for computational screening for functional compounds. With the ZINC ID at hand, the ZINC web site is contacted and from there the URL parsed the refence to the real data. This workflow does not scale for regular docking applications. One would retrieve a collection of data inst...

• Download

This workflow experiments with the partial execution of jobs on a computational grid. The workflow elements "mustang" and "boxshade" are executed on grid nodes. Access to these resources is orchestrated with the plugin available on http://grid.inb.uni-luebeck.de. Please contact the author of this workflow for access permissions.
