<div dir="ltr">Hi Madi,<div><br></div><div>I got it working now. I think that my DEM is so big (one country). I created a subset and it is now working. Is there a way where I can just choose my region of interest from my country-wide DEM and then process it? Right now what I am doing is to clip the DEM to create a subset and process it.</div>
