<div>Hi Markus,</div>
<div> </div>
<div>May be you are right (Vista issue!). Two month ago I was trying to run the same steps on grass, but I was expecting that new OSGeo4W release included some fix for that. :-(</div>
<div> </div>
<div>Anyway, thanks for your time.</div>
<div> </div>
<div>Any colleague that could suggest a way of I extract some geomorphometry features (sensu Tom Hengl!) from "large" DEM (10,000x6,000), please let me know.</div>
