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
