Description
The Taverna team are pleased to announce that Taverna 2.2.0 workbench and command line tool are now available for users to
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 a command line tool that allows you to execute workflows outside of the workbench. The command line tool is available either bundled with the workbench or as a separate download.
Tutorials and examples
Tutorials for Taverna are available on the Taverna
website
.
Example workflows can be found under the Starter pack tab in the myExperiment section of the workbench. They can also be downloaded from the myExperiment
website

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. An updated and more detailed list can be found in our issue tracker
Jira
.
Taverna and Java
Taverna requires the Java Runtime Environment (JRE) version 5 or 6 from Sun. No other versions of Java have been tested. You can download Java from
Sun
.
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
