[galaxy-dev] workflow_execute_parameters.py

Dear developpers, I'm trying to launch a small workflow using the api script workflow_execute_parameters.py I have 2 steps: the input data step and a second step which needs a parameter called prefix. The workflow is attached to this email. I get an error on the parameters inputs which asks me to specify information about an 8th step (which does not exist) Is there a test case available to use this script ? Please keep me informed on that. Have a nice day, -- Olivia Doppelt-Azeroual, PhD Tel: 92 15 CIB - Institut Pasteur
