I am trying to use Ordered weighted averaging to sum up values across different raster overlays in QGIS 3.4.4, but I get this error:
Traceback (most recent call last):
File "C:/PROGRA~1/QGIS3~1.4/apps/qgis/./python/plugins\processing\algs\saga\SagaAlgorithm.py", line 217, in processAlgorithm files.append(parameters[param.name()].source()[:-4] + 'sgrd') AttributeError: 'list' object has no attribute 'source'
I have already tried to use Raster Calculator by SAGA, Raster analysis and GDAL, and GRASS' r.series, but either get an error or get a blank map. I have selected no-data value for 1 layer only, so I should get a result even if the areas don't overlap.
