Your attachment was not included, but it is a general problem in Taverna 1 that you need to Remove and Create the iteration strategy if you modify the ports of a processor, including connecting or disconnecting to the input ports. (The default "empty" strategy would still work, though, as it's implicitly created when you press Run). This issue is not likely to be fixed in Taverna 1. For some reason this was not already in Jira, but I added it as http://www.mygrid.org.uk/dev/issues/browse/TAV-781 In Taverna 2 the iteration strategy is always updated when you modify the ports. New ports are simply added to the bottom. Note that in some complex cases when you remove or disconnect a port, you could end up with empty dot- and/or cross products, so it's always a good idea to revisit the strategy after such editing. http://www.mygrid.org.uk/dev/issues/browse/T2-73 says that the user interface should encourage configuring an iteration strategy when a processor has more than one input port connected. -- Stian Soiland-Reyes, myGrid team School of Computer Science The University of Manchester ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
