[galaxy-dev] Deseq2 wrapper question

Hi All,

we are making a wrapper for deseq2, and there is a step where control/experimental conditions need to be determined. For example, it would be a column like the following in the input file

Type CTC CTC LM LM PT PT

and we want the select list to contain

CTC LM PT

In other words, we want to filter out the 'Type' and have only distinct ones in the select list. We could make it in two steps, generate a intermediate file for this but it would be nice that we could directly retrieve the distinct types to make the list. I took a look at the tool config wiki, but didn't see anything (maybe because it was a quick scan). Does anyone have any tip on this? we'll really appreciate.

Thanks, Rui
