I am running the Sediment Retention model, and everything is working except for the erosivity raster. When I use a single-value dummy raster, the model works perfectly, but when I use the real file it yields all negative values. The only notable differences I can find with this raster I'm trying to use and erodibility rasters that I have used in the past, is that this one is a 32-bit, level 1 pyramid building, and has no attribute table, while past rasters have been 8-bit unsigned, level 4 pyramid building, with attribute tables. According to the 'build raster attribute table' tool, my layer is also a multi-band (versus single-band raster). Could the number of bands be the problem? I have been unable to figure out how to convert it into a single-band raster.
