Hi, We have installed a customised version of the BioVeL portal which uses Taverna Player to facilitate workflow execution online. Our aim is to introduce the tool to spanish speaking users (biotechnology scientists specifically).
The portal is available at http://lvbupp.at.uppuebla.edu.mx/. Overall, the portal works and lets users execute workflows. However, workflows with interactions seem to have problems. We have tested and found two kinds of problems: interactions not shown properly and responded interactions not being registered. In both cases, the problem is that the workflow will not continue execution unless the interactions is responded by the user and as a result the workflow cannot finish. For an example of the first case, we have tried running the "Bayesian Phylogenetic Inference: Select Model For Me - Submission" workflow ( http://www.myexperiment.org/workflows/3410.html). The firs interaction cannot be found so the popup shows a blank screen and the state of the run reamins as "Waiting for user input". For an example of the second case, we executed the "Matrix Population Model analysis v12" workflow (http://www.myexperiment.org/workflows/3686.html). The first interaction is presented correctly, After selecting values and pressing on confirm, the popup shows the legend stages submited However, nothing else happens, the popup stays on and the state of the run remains "Waiting for user input". In both cases, the runs stay on and is not possible to continue exevution, consequently they must be cancelled. I think the problem needs to be addressed by ensuring that Taverna Player maps interaction URLs correctly so that the workers that poll the interaction queue and Taverna server can detect which interactions have been answered. In the mean time ther should be a work around so that routes interpreted correctly. If any one has had a similar problem or is addressing a similar issue, or knows of a workaround, please let us know. Regards Abraham
