Hi Julien,
You need to input a (polygon) shapefile to define regions of interest for which
the metrics will be calculated. Basically, the usage should be the same as when
using a shapefile but just that the output is not another shapefile but a ascii
file.
Hope that makes sense and let me know if you have any other issues.
Best wishes,
Pete
