Hello, I’m having a problem with the NDR model, I’m not sure if it’s the Nutrient Runoff Proxy (I’m using the QF\_1.tif raster of SWY results), or maybe it is something else.

Attached you can find the log file with the error.

Thank you for the help in advance,

Diego

Hi Diego,

I think we might have fixed this in a recent development version of InVEST. Could you try this development build and see if it corrects the issue?

Here’s the download link: [https://storage.googleapis.com/releases.naturalcapitalproject.org/invest/3.7.0.post537%2Bh1fb1875d7f96/InVEST\_3.7.0.post537%2Bh1fb1875d7f96\_x86\_Setup.exe](https://storage.googleapis.com/releases.naturalcapitalproject.org/invest/3.7.0.post537%2Bh1fb1875d7f96/InVEST_3.7.0.post537%2Bh1fb1875d7f96_x86_Setup.exe)

Thanks!  
James
