Content-Type: text/plain; charset="us-ascii"I've done something incorrectly but cannot find what that is.
Ran r.water.outlet and produced the output basin map. Then I applied
r.null to that map setting nulls to zeros.
r,water.outlet produces a map with zeros instead of nulls, so you better must apply r.null to set zeros _to_ nulls
Next I applied r.to.vect to that
map (with the '-s' option) setting feature to area.
Also, try without '-s'
