This graphical representation of a workflow in Taverna was taken directly from workflow 377 at the myExperiment site. It requests two PDB IDs to retrieve the respective protein structure and present it to the mustang protein structure alignment tool. Its result files are directly offered also as outputs of the workflow. It is only one alignment that is passed throught the tool boxshade for pretty-printing.
