Excellent, thanks Paul. For the benefit of others - the Ruby Gems that Paul is referring to are available for anyone to use, from here:
For Taverna 1: http://github.com/mannie/taverna1-gem/ For Taverna 2 (t2flow) http://github.com/mannie/taverna2-gem/ Cheers, Jits Paul Gordon wrote: > The gems worked like a charm (so to speak), thanks.
