Here is what I think is strange though about your explanation,
Markus: If I first mask a watershed produced with r.water.outlet and
then use r.watershed to produce subbasins, it doesnt include the
entire area of the watershed but leaves small areas out, although
these areas belong to it. Is this a threshold problem?<br>

last year you asked me whether the r.watershed output is not
aligned to the r.water.outlet output in GRASS7 (s.b.). Ie.
it leaves small areas out. Back then, I wasnt using GRASS7,
but I can confirm now that it still does it and it is still
rather annoying. Have you ever heard of the reasons or
attempted to fix this?<br>
Thanks,<br>
