Description
I am using Modeler in QGIS 2.2 and it gives me an error when I use SAGA algorithms. The error is:
Oooops! The following output layers could not be open
Sum: C:\\Users\\Lia\\AppData\\Local\\Temp\\processing\\27c6ca3a520e41108410d3a06c990490\\RESULTALG0.tif
The above files could not be opened, which probably indicates that they were not correctly produced by the executed algorithm
Checking the log information might help you see why those layers were not created as expected.
GRASS algorithms are working well but SAGA doesn't. I am using Grids Sum algorithm.
Hope you help me.
Best regards,
LDuarte

confirmed, had several issues this past day had to resort to GRASS algorithms instead

Thanks for check this.
So, SAGA algorithms, especially grids calculator, doesn't work in QGIS 2.2 right?
I have to use GRASS?
#3
Updated by Filipe Dias over 10 years ago
Do SAGA algorithms work outside of the Modeler?
#4
Updated by Barbara Duarte over 10 years ago
Yes, outside Modeler all SAGA algorithms works fine.
Inside Modeler, SAGA algorithms as Grids Sum, Grids Product and Raster Calculator, doesn't work.

Go to Plugins -> Manage and Install plugins -> Settings -> activate "Show also experimental plugins"
Then, upgrade "processing" and report back please.

Do you mean restart QGIS with "upgrade processing" after activate "Show also experimental plugins"?
I did what you said but I get the same error.

- Target version changed from Version 2.2 to Version 2.4
The issue seems to be that in the modeller the output (SAGA) raster is not defined, example:
Algorithm starting...
Prepare algorithm 0: Grids sum
Running Grids sum [1/1]
Parameters: GRIDS =None
grid_calculus "Grids Sum" -RESULT "/tmp/processing/e6a09432c0804993946df728166697b0/RESULTALG0.tif.sgrd"
io_gdal 1 -GRIDS "/tmp/processing/e6a09432c0804993946df728166697b0/RESULTALG0.tif.sgrd" -FORMAT 1 -TYPE 0 -FILE "/tmp/processing/e6a09432c0804993946df728166697b0/RESULTALG0.tif"
The value for the option 'GRIDS' must be specified.
while not in the modeller it is, example
Algorithm Grids sum starting...

Is there a way to use SAGA algorithms through Modeler?

If there is a bug this must be fixed. Once fixed a new updated version of the toolbox can be immediately shipped as plugin update. If you are in a hurry to have a fix then you can hire one of the developers. If you are in Portugal you can drop me a line.

Ok.
No, I can wait for the new version.
Hope it is fixed.
Thank you for the attention.
