Here is the result:
projection: 0 (x,y)
zone:       0
north:      5682231.5
south:      5679169.5
west:       469641.5
east:       472228.5
nsres:      1
ewres:      1
rows:       3062
cols:       2587
cells:      7921394

I must admit that I am quite new in GRASS, and I don't master all the concepts. Is the raster too big? Do I have to increase the memory allocated? In this last case, I don't know at all which module to use.

It doesn't work for both ^^ It works until I put 7, but I would like to make it as written in the manual, to be precise enough.
