Hi @mhyuan -
I wonder if the error is related to the LULC input “w001001.adf”. It looks like this is an ESRI GRID raster, so try entering the associated file “hdr.adf” and see if that helps. Alternately, I advise converting the file to a TIFF, like your erodibility and erosivity rasters are, since they’re easier to work with in a lot of ways, and it’s much more obvious which file to enter into the model.
