Pattern: Return errors instead of null (1)

• Download

 As Taverna can't (currently) handle null (see http://www.mygrid.org.uk/dev/issues/browse/TAV-653) - in Taverna 2 one can instead return exceptions on individual ports and inside lists. Exceptions are registered as error documents by Taverna, and are passed along. The ErrorBounce layer of processors downstream will prevent execution if they see this 'null'-exception - as showed in this example that the string concatination is just run for the two list elements that are not exceptio...

Look up concept URI from freetext, e.g. "aspirin", find compound pharmacology and their target info. For each target, blast+tree on its sequence - if any. Uses the Open PHACTS API https://dev.openphacts.org/docs/1.5. Notice that in tihs workflow, most concepts won't have compounds, and most compounds won't have targets, and most targets won't have a sequence - Open PHACT API wise this means this workflow would be propagating 404 Not Found errors. Until there is a Local worker to filter out...

Refresh SPI after plugin installation (1)

• Download

This workflow hacks into Taverna's plugin system to force update the net.sf.taverna.t2.workbench.views.results.saveactions.SaveAllResultsSPIRegistry SPI, which means it is possible to install/update the Taverna PROV plugin without restarting. This is needed to enable live update of this plugin, because there is a bug in Taverna 2.4 and below where the SPI registries are not updated correctly after installation of a plugin.

WCP-04 Exclusive choice - if/else branching (1)

• Download

The choice of executing choiceA or choiceB is determined by using String_List_Intersection and String_List_Difference. If in="true" then the intersection will yield a non-empty list, triggering execution of choiceA. This list will however not differ from the input, and so choiceB will iterate over an empty list (ie. not execute). Note how using 'difference' for the else-case here means that if you run the workflow with in="bob", choiceB would still run. Some early if/el...
