Interesting – this was a workflow with exactly 1 step – the “add a column” tool. I looked in my database/files/000 directory, and there was no dataset id 53 – would that be an id in the history_dataset_association table?

In any case, I would like to be able to start a workflow for the user without interfering with any notion of the “current” workflow they may have open in their browser. Is that possible now, or do I need to:

- Create a history and set it be the “current” history (how is that done?)

- Import my datasets into it

- Fetch the form (which will autopopulate the file inputs from the “current” history

- Let them launch it by submitting the form?

John, the prefixes like "22|" are added to the inputs associated with each step, so that they can be separated back out. In this case, the chunk of HTML you have pasted likely corresponds to the 22nd step of the workflow. 

53 on the other hand should be a dataset id from the current history (unencoded in this case).

I’d like to integrate with Galaxy and launch workflows, and I am hoping to reuse  Galaxy’s support for prompting the user for items that are tagged as being set at runtime. It looks to me that I could load the workflows/run page in a frame on my app (on the same server) and reuse it.

The problem I’m having is that I don’t understand how the parameters for the input files are encoded. For example, here is one for adding a column to a dataset:

<select name="22|input" last_selected_value="53">

<option value="53" selected>1: Add column on data 6</option>

</select>

<input type="hidden" name="22|__force_update__input" value="true" />

</div>

<div style="clear: both"></div>

</div>

What are 22 and 53? They don’t seem to correspond to dataset IDs.

Is there a way that I can encode data library IDs such that I can submit this form and have Galaxy run the workflow with the right files in a new history?

Thanks!
