Hi @KLI - If your NoData value is set, and you’ve verified that all of the values in your land use/land cover map have an entry in the biophysical table, then I’m not sure what’s causing this error. If you can send me your data I’ll take a look at it. The best way to do it is this: 1/ In InVEST Workbench, go to the tab where you’re entering your model inputs. 2/ Click on “Save As…” in the left side of the screen. 3/ In the “Datastack options” window that appears, click on “Parameters and data”. 4/ Give the output file a name (leaving it as the default is fine too), and make sure that the file extension is “.tgz”. 5/ Save the file and send it to me at swolny@stanford.edu Thanks! ~ Stacie --- _[View the full topic](https://community.naturalcapitalalliance.org/t/sdr-error-exception-encountered-in-raster-calculator/3715)._
