Using QGIS 1.8.0 and SAGA When trying to use the IDW function from SEXTANTE SAGA 2.1.0 64-bit, I get the following error: Could not load layer: C:/test.tif.
This error seems mysterious to me, any ideas?
SEXTANTE error logs
With vector layer loaded as a PostGIS layer:
Could not load model watersheds.model

With vector layer loaded as a shapefile:
sextante.runalg("saga:inversedistanceweighted","C:/test.shp","score",0,0,2,1,0,100,0,0,10,"2297980.80156,2325375.34865,108272.496186,135921.444199",0,None)
System
I am using QGIS 1.8.0 with SAGA 2.1 b3 64-bit on Windows 8 64-bit.
No problems running it directly in SAGA without SEXTANTE
I can't figure out how to import the raster .sgrd file back into QGIS… Somehow the points loaded into SAGA are skewed at an angle.. that's for another question
Update
Updated to QGIS v.1.9.90. When activating SAGA under SEXTANTE, I get the following error. I get the same error when I choose any of SAGA's function under SEXTANTE's toolbox.
An error has occurred while executing Python code:

Best Answer
two things:
first, i recommend to you use the latest QGIS master with the latest SEXTANTE.
Second, enable SAGA logging in the SEXTANTE configuration options, so you can share with us what is happeningn in SAGA (the log you pasted is not the SAGA console output)
Hope this helps
