Gene set enrichment analysis (Affymetrix probes)

This workflow is designed to perform Gene Set Enrichment Analysis, GSEA, as it is described at http://www.broadinstitute.org/gsea/index.jsp. As input, the normalized data with Affymetrix probeset IDs can be submitted.
First, the input files are subjected to fold-change calculation. The table with probeset Ids and calculated fold change values is converted into a table with Ensembl Gene Ids. At the next step, the Ensembl genes are annotated with additional information, gene description and gene symbols. Finally the annotated Ensembl genes are subjected to GSEA. Enrichment analysis is done in parallel by the following ontologies: GO biological processes, GO cellular components, GO molecular functions and by the Reactome pathways.

What is the geneXplain type?

The geneXplain platform is an online toolbox for a broad range of bioinformatic and systems biology applications. It is developed by geneXplain GmbH. The technology behind the geneXplain platform is BioUML (www.biouml.org), which has been built, improved and supported for many years at the Institute of Systems Biology in Novosibirsk. The individual workflows (geneXplain type), or Bricks, are unified under a standardized interface.
To run the workflows you just need to register for a free account here:

http://www.genexplain.com/genexplain-platform-registration

You get a password from BioStore to login the platform. It is open for everyone.

After clicking the workflow link (bottom) you can immediately enter the platform and execute the workflow via simple drag and drop of uploaded data files in your project.
