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. Next I applied r.to.vect to that
map (with the '-s' option) setting feature to area.
When I look at the aspect map overlaid by the sub-basin map I see the 5
extraneous cells that should not be there. You can see them on the attached
screen shot.
This did not happen the last time I used r.water.outlet, and the drainage
map does not suggest to me why these 5 cells are included.
Help would be appreciated in learning what happened and how to get this
tail off the map.
Since now a vector, can you select and delete those extraneous blocks?

Mark,
I've tried, by selecting both 'delete features' and 'delete nodes', but
when I redraw the display they're still there. The wxPython GUI help web page
doesn't tell me just how to do this. I exit and confirm the deletions, but
they're still there.
I haven't used the python GUI much. How about v.digit to graphically delete the blocks?
