Created: Wednesday 07 July 2010 17:53:56 (UTC)


The Taverna team are pleased to announce that Taverna 2.2.0 Workbench and the Command Line Tool are now available for download.

Taverna 2.2.0 includes improvements to the Workbench user interface and gives users greater control over the workflow engine. Here are a few of the new features in the Workbench:

  • Loading and sharing of service sets
  • Ability to load and edit workflows that contain services that are offline
  • Reporting on the state of the workflow
  • Tabular representation of a workflow run
  • Retrying and parallelization of service calls
  • Consistent representation of the intermediate and workflow results
  • Pause/resume/cancel of a running workflow

Taverna 2.2.0 also includes the Command Line Tool that allows you to execute workflows outside of the Workbench. The Command Line Tool is available either as a stand-alone download or bundled with the Workbench.

Tutorials and examples

Tutorials for Taverna are available under the Taverna 2.x documentation.

Example workflows can be found under the Starter pack tab in the myExperiment perspective of the Workbench. They can also be downloaded from the myExperiment Web site at

Known issues

Although Taverna 2.2.0 contains many improvements there are some known issues with it. These are detailed in known-issues.txt in the download bundle. An updated and more detailed list can be found in our issue tracker Jira at:

Taverna and Java

Taverna requires the Java Runtime Environment (JRE) version 5 or 6 from Sun. No other versions of Java have been tested.

Java on Linux

Some Operating Systems, such as Ubuntu, come with the Gnu GCJ version of Java that cannot be used to run Taverna due to bugs in GCJ.

To download Sun Java 6 for Ubuntu, start a Terminal and type the following:

sudo apt-get install sun-java6-jre

and follow the instructions. You might also have to switch the default Java installation by running something like

sudo update-java-alternatives -s java-6-sun

Read more details about Taverna’s system requirements, in particular how to set the location of the Graphviz binary dot if needed.
