Why is SAGA from the Processing Plugin not recognised?

Question

Similar to SAGA algorithms don't work in QGIS 2.8 except that SAGA does not appear at all in the Processing Toolbox:

As a check, I used the Python Console with the following code to see if any SAGA tools are available (which they're not):

import processing
processing.alglist()

I've installed QGIS 2.8.2 Wien via the OSGeo4W Network Installer, 64-bit and downloaded the latest version of the Processing Plugin (v2.9.3).

Answer 1

Just to add to the earlier answer...

You can find the field for the path here -

Processing > Options > Providers > SAGA > SAGA Folder:

Answer 2

I was having a similar problem, but I kept running into trouble re-pathing the SAGA folder. For some reason, the folder selection dialog kept forcing me to a file and inserted all of the folder separators as forward slashes: C:/Program Files (x86)/QGIS 2.14/apps/saga_2.1.4_x64/saga_cmd.exe

I manually edited to C:\Program Files (x86)\QGIS 2.14\apps\saga_2.1.4_x64, and that fixed my geoalgorithms.

(I rolled back to SAGA 2.1.4 because of this question: "Unknown option 'CAREA'" in SAGA Catchment area algorithm for QGIS. I don't think that was my problem, but everything I need is working now, so I'm afraid to change it back!)

Answer 3

I simply had to change the SAGA path to where it was installed (which in my case was in the OSGeo4W directory):

C:\OSGeo4W64\apps\saga

Now have the correct SAGA algorithms.
