Implementing bioinformatic workflows within the bioextract server.

Computational workflows in bioinformatics are becoming increasingly important in the achievement of scientific advances. These workflows typically require the integrated use of multiple, distributed data sources and analytic tools. The BioExtract Server (http://bioextract.org) is a distributed service designed to provide researchers with the web ability to query multiple data sources, save results as searchable data sets, and execute analytic tools. As the researcher works with the system, their tasks are saved in the background. At any time these steps can be saved as a workflow that can then be executed again and/or modified later.
