Hello all,

I'm getting the python error below when trying to run the SCP Accuracy 
Assessment. I do not know what to make of it.

I'm trying to assess a classified image (a single band raster with 6 
macro-classes numbered 1 to 6 along with an 'unclassified' class numbered 0). 
I'm assessing this with ROIs in vector form for the 6 classes. 

Of note: considering the error (list index out of range), I was suspecting that 
maybe I needed to create reference data for the 'unclassified' class (which is 
counter-intuitive) so I made up a fake ROI for this class, but that did not 
correct my problem.

Any clues as to what I can do?
