Dear Dannon, Thank you for your answer, it works better now that I know the steps ID for my workflow. I have another question though. The second step of my WF uses a parameter input named "prefix". I really need to specify it when I launch the WF using the API. When i display the WF using the url you gave me, the parameters prefix, is not there and when I use this in my command line, the specified Value is not read by Galaxy. python workflow_execute_parameters.py 43359c833b8977b01d6237d9b839dc27 http://127.0.0.1:8080/api/workflows f2db41e1fa331b3e a799d38679e985db '10=hda=52ea4fd71e9f7c3f' 'param=export_sbw=prefix=test' Could you help me on that ? How do I give a value to a parameter if it does not appear in the WF description ?? Thanks in advance, -- Olivia Le 23/04/14 18:40, Dannon Baker a écrit :

Hi Olivia!

It's probably talking about the "workflowstep" object with identifier 8. If you request the description of this workflow via the API (http://yourgalaxyinstance.org/api/workflows/<the id of this workflow>"), you'll be given the exact step identifiers to use. In other words, unless this is the first workflow ever created on a brand new galaxy instance, your step ids will not be 0 and 1.

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,

Dear Dannon, when the parameter (that I need to fix) is 'set at runtime', the value that it gets is: __lt__galaxy.tools.parameters.basic.RuntimeValue ---- python workflow_execute_parameters.py 43359c833b8977b01d6237d9b839dc27 http://127.0.0.1:8080/api/workflows f2db41e1fa331b3e a799d38679e985db '14=hda=52ea4fd71e9f7c3f' 'param=export_sbw=prefix="test"' ---- the parameter prefix needs to be set at the value "test" (I tried without the quotes also) --- Here is what you asked for:

{ "id": "f2db41e1fa331b3e", "inputs": { "14": { "label": "input Dataset", "value": "" } }, "model_class": "StoredWorkflow", "name": "export_WF", "published": false, "steps": { "14": { "id": 14, "input_steps": {}, "tool_id": null, "type": "data_input" }, "15": { "id": 15, "input_steps": { "inputs_0|input": { "source_step": 14, "step_output": "output" } }, "tool_id": "export_sbw", "type": "tool" } }, "tags": [], "url": "/api/workflows/f2db41e1fa331b3e" }

---- as you can see, the parameter called prefix, is not there. Thank you for your help -- Olivia Le 25/04/14 19:49, Dannon Baker a écrit :

Olivia,

Is the parameter set to 'set at runtime' when you view the workflow in the editor? Could you send me the workflow json (just the http://127.0.0.1:8080/api/workflows/<workflow_id>/ bit)?
