AttributeError

Been trying to crack it the whole day. Exported the raster both in ArcGIS and QGIS, still get the same error. Everything is fine until i get to the CA simulation and get the following error:

An error has occurred while executing Python code:

AttributeError: 'NoneType' object has no attribute 'getBandGradation'
Traceback (most recent call last):
File "C:/Users/Nemanja Nikolic/.qgis2/python/plugins\molusce\moluscedialog.py", line 528, in simulationDone
grad = res.getBandGradation(1)
AttributeError: 'NoneType' object has no attribute 'getBandGradation'

And this is in from the message tab:

Thanks

P.S. Using CORINE 2000 and 2006 tiff 100x100 files

The root of the issue somehow connected with ANN prediction:

[Sun Oct 30 2016 20:15:13] ERROR: An unknown error occurs during ANN prediction

The model can't process input data and finally returns None as the result of prediction/simulation.

Could you provide links to you input files?

Figured it out. The Raster had a preset Non Value at 45, and i was setting it to 0 when i was doing the Raster Clip in QGIS. It seems to have fixed the problem. :) I changed it to 45, and it works.

But still getting strange results of simulation. Here are the files i have been using and the simulation result.

MOLUSCE Test.zip

I intentionally used ANN because my Spatial variables aren't the greatest, so i was looking for methods that would bypass them. Does the CA Simulation take the Spatial variables into consideration if you choose ANN or Logistic regression? :)

Try brand new MOLUSCE 4 for QGIS 3 and let us know if the problem persists
