I am currently looking for an open source alternative to eCognition. I know the

Thank you for responding.
You are right. I installed grass with sudo and now tried as a normal user. It
seems now that the permission and owner should be right.
However, despite this, I have got a new error message today:

Checked out revision 41157.
Compiling ps.output...
How can r.region put my image in place? Because it's a geostationary data so
the image corners don't have the same coordinates (e.g. Top Left and Top
Right don't have the same latitude). But I do have some GCP's for the image.
So r.region doesn't help me (as far as I can see).

Nikos,
as Maciek said, your image seems to need warping, so I fear you have no
other solution than georectify it.

I've done something incorrectly but cannot find what that is.

r.null to that map setting nulls to zeros. Next I applied r.to.vect to that

Mark,
I don't know.
It is my understanding that r.drain overcomes pits/sinks in a DEM by
traversing lowest locations until goes off map.
I did not use r.drain, but r.watershed.

I stated it backwards. I understand that the setnull command does just
