hi,  
I am running a sediment delivery ratio model. it shows “TypeError encountered: not a string”. can you kindly check it for me?

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.

Dear Stacie,  
Thanks for your quick response. I have done something according to your suggestion. However, it shows similar error information. Can you kindly check it for me?

Hi @mhyuan,

Sorry to see you’re still having troubles. A few things:

1. Could you download, install, and run the latest version of InVEST and SDR that has a pretty significant bug fix? [InVEST 3.8 SDR-BugFix](https://storage.googleapis.com/natcap-dev-build-artifacts/invest/phargogh/3.8.0.post171+g059df5bf/InVEST_3.8.0.post171+g059df5bf_x86_Setup.exe)
2. Can you check that your input rasters and watershed shapefile are properly projected with valid Coordinate Systems? It appears that at least one of the input files is not behaving correctly.

Cheers,

Doug

Hi,  
I have carefully checked input files and all the problems have solved out. Thanks for your suggestion.  
I am working on another one - Habitat Quality. It shows different errors. I have upload messages here. Can you kindly check it up for me?

Hi @mhyuan,

Glad the SDR issue was resolved and happy to answer questions on Habitat Quality. However, _could you post again under a new topic / thread_? We try to keep each question isolated so that it is easier for people to follow and find later. I am going to close this topic / thread and look for your new post!

Thanks!

Doug
