please test the sample from the manual with the NC sample data set [1], then follow the example workflow with your data and report the results and the used commands (g.region, r.watershed, r.water.outlet).
Helmut, Yes, that works here, too. Of course, my data also worked until yesterday afternoon and why it now fails is what I need to discover. In the NC data set from mapset user1 I selected 'elevation' as input to r.watershed and 'drainage' as output. For r.water.outlet the input was 'drainage,' the output 'watershed,' and the coordinates a point I selected that looked like a basin outlet. When I displayed 'watershed' a small yellow area appeared. This is how it used to work here, too. Here's the region and commands used on my data: From project location:
g.region -p
projection: 99 (NAD83(HARN) / Oregon North) zone: 0 datum: nad83harn ellipsoid: grs80 north: 175430.80940854 south: 174426.61003591 west: 2295620.05945154 east: 2296197.40538338 nsres: 1.00019858 ewres: 1.00059954 rows: 1004 cols: 577 cells: 579308
g.list type=rast
bare_earth
r.watershed elev=bare_earth drain=drainage --overwrite
r.water.outlet in=drainage out=watershed coord=2295821.27858,175258.094514 -- overwrite
But, now when I use the GUI icon to display 'watershed' nothing appears. Using d.mon start=wx0; d.rast map=watershed also displayed nothing. Something changed. How do I trace the reason to the source?
