It seems that the current region has more than 20 billion grid cells. Does this match the input to i.segment? You might want to check the current region settings and compare them with extents and resolution as reported by r.info on the input to i.segment. Please provide the output of g.region -p and r.info if you want more detailed help. Markus M > > -- > Paul J.
