Hi Euan,
Thank you for reporting this problem, and for reporting the complete output of the tool along with data that reproduce it. I am sorry it has cropped up again. It is a bug in MGET. Attached is a file that fixes the problem. Could you please:
1. Close all ArcGIS programs. 2. Replace the file C:\Python27\ArcGIS10.3\lib\site-packages\GeoEco\SpatialAnalysis\Diversity.py with the attached one. Unfortunately you may need to be admin on the machine to do this. 3. Retry the problem.
Please let me know how it goes. This fix will appear in MGET 0.8a62 and later.
Best, Jason

Hi,
The diversity index is exactly what I need, but, as per the title, I'm having a problem executing it. Specifically, the tool seems to encounter a problem when bringing the results back to ArcMap (10.3.1). The full error log is quoted at the end of the email.
A similar (identical?) issue was raised in 2013. Following on from the troubleshooting there, I created a second random zone of interest polygon. This, unfortunately, did not alleviate the situation.
The other solution mooted there was that maybe it's something to do with R? I've not tried downgrading our version of R (3.1.1) just yet, as I do not have admin rights to the machine. As such, I'd rather have a confirmation that this is the case before dragging IT into the situation!
I've attached the sample data I was testing on, if that is of any use.
Many thanks for any help, Euan Forsyth
