{{Example farm|date=February 2012}}
A '''bioinformatics workflow management system''' is a specialized form of [[workflow management system]] designed specifically to compose and execute a series of computational or data manipulation steps, or a [[workflows|workflow]], that relate to [[bioinformatics]].
There are currently many different workflow systems. Some have been developed more generally as [[scientific workflow system]]s for use by scientists from many different disciplines like [[astronomy]] and [[earth science]]. All such systems are based on an abstract representation of how a computation proceeds in the form of a directed graph, where each node represents a task to be executed and edges represent either data flow or execution dependencies between different tasks. Each system typically provides visual front-end allowing the user to build and modify complex applications with little or no programming expertise.<ref>{{cite doi|10.1002/cpe.993|noedit}}</ref><ref>{{cite doi|10.1145/1084805.1084814|noedit}}</ref><ref>{{cite doi|10.1109/CIBEC.2008.4786077|noedit}}</ref>
==Examples==
In alphabetical order, some examples of bioinformatics workflow management systems include:
* [[Anduril (workflow engine)|Anduril]] bioinformatics and image analysis
* Anvaya: Anvaya is a software application consisting of interface to Bioinformatics tools and databases in a workflow environment, to execute the set of analyses tools in series or in parallel.<ref>{{cite pmid| 22809419|noedit}}</ref>
* [[BioExtract]]: a web-based system for querying biomolecular sequence data, executing analytic tools on the resulting extracts, and constructing workflows composed of such queries and tools.
* [[BioBIKE]]: a Web-based, programmable, integrated biological knowledge base<ref>{{cite pmid|19433511|noedit}}</ref>
* [[UGENE]] provides a workflow management system that is installed on a local computer<ref>{{cite pmid|22368248|noedit}}</ref>
* Chipster: a user-friendly analysis software for microarray data<ref name=chipster>{{cite pmid| 21999641|noedit}}</ref>
* [[Discovery Net]]: one of the earliest examples of a scientific workflow system, later commercialized as InforSense which was then acquired by IDBS.
* [[Galaxy (computational biology)|Galaxy]]: initially targeted at [[genomics]]<ref>{{cite pmid| 20738864|noedit}}</ref>
* GeneProf: web based functional genomics experiments, e.g. RNA-seq or ChIP-seq<ref>{{cite pmid| 22205509|noedit}}</ref>
* [[KNIME]] the Konstanz Information Miner<ref>{{cite doi|10.1016/j.compbiolchem.2007.08.009|noedit}}</ref>
* [[OnlineHPC]] Online workflow designer based on [[Taverna workbench|Taverna]]
* SeqWare: Hadoop Oozie-based workflow system focused on genomics data analysis in cloud environments{{citation needed|date=October 2014}}.
* Tavaxy<ref>{{cite doi|10.1186/1471-2105-13-77|noedit}}</ref> A cloud-based bioinformatics workflow system that integrates features from both Taverna and Galaxy for NGS data analysis.
* [[Taverna workbench]]:<ref>{{cite doi|10.1093/bioinformatics/bth361|noedit}}</ref><ref>{{cite doi|10.1093/nar/gkl320|noedit}}</ref> an early ___domain-independent system widely used in bioinformatics and other areas of [[e-Science]]
* [[VisTrails]]<ref>{{cite doi|10.1109/VISUAL.2005.1532788|noedit}}</ref>
==Comparisons between workflow systems==
With a large number of bioinformatics workflow systems to choose from, it becomes difficult to understand and compare the features of the different workflow systems. There has been little work conducted in evaluating and comparing the systems from a bioinformatician's perspective, especially when it comes to comparing the data types they can deal with, the in-built functionalities that are provided to the user or even their performance or usability. Examples of existing comparisons include
* The paper "Scientific workflow systems-can one size fit all?",<ref>{{Cite doi|10.1109/CIBEC.2008.4786077|noedit}}</ref> which provides a high-level framework for comparing workflow systems based on their control flow and data flow properties. The systems compared include [[Discovery Net]], [[Taverna workbench|Taverna]], Triana, [[Kepler scientific workflow system|Kepler]] as well as Yawl and [[Business Process Execution Language|BPEL]].
* The paper "Meta-workflows: pattern-based interoperability between Galaxy and Taverna" <ref>
{{Cite doi|10.1145/1833398.1833400|noedit}}</ref> which provides a more user-oriented comparison between [[Taverna workbench|Taverna]] and [[Galaxy (computational biology)|Galaxy]] in the context of enabling interoperability between both systems.
* The infrastructure paper "Delivering ICT Infrastructure for Biomedical Research" <ref>
