Hi,<br>
Thanks for your answers, here the command line I run<br>
r.basin map=Ghiandone_DEM@Silvia prefix=out coordinates=368450.0,4954025.0<br>
dir=Silvia threshold=1000 --overwrite<br>
<br>
<br>
</span>In your command line, is the raster map "Silvia" the flow direction raster,<br>
that was created from the DEM?<br>
<br>
