Hello SWAT user,

I tried using the predefined watershed option in QSWAT after I had successfully loaded the DEM, watershed boundary, and stream reaches. I got an error that reads "cannot generate slope file from dem" when I ran the "recalculate" option. What might be the problem?

I have attached the screenshot of the error.
