Research paper thumbnail of Workflows in bioinformatics: meta-analysis and prototype implementation of a workflow generator

BMC bioinformatics, 2005

The structures of these workflows are defined by a scaffold of syntactic, semantic and algebraic objects capable of representing them. Despite the proliferation of GUIs (Graphic User Interfaces) in bioinformatics, only some of them provide workflow capabilities; surprisingly, no meta-analysis of workflow operators and components in bioinformatics has been reported.

Research paper thumbnail of Bioinformatic workflows: G-PIPE as an implementation

Our implementation goes beyond macro capacities currently in PISE. As the entire analysis protocol is defined in XML, a complete bioinformatic experiment (linked sets of methods, parameters and results) can be reproduced or shared among users. We also discuss the role of ontologies as as guidance systems in order to provide users with the possibility to define abstract work-flows, and execute them. A relevant baseline ontology is presented. Availability: http://if-web.imb.uq.edu.au
