I have read in the tutorial about the "split and unfold", where can I find the recipe?

Hi,

"Split and Unfold" is a processor of the visual Preparation recipe / Analysis, not a separate kind of recipe. You can find it by clicking the "Add" button from the Analysis or Preparation recipe script screen.

Specific doc about this processor can be found here: http://doc.dataiku.com/dss/latest/preparation/reshaping.html

Regards,
