Hi,

I am unable to run Kringing functions from SAGA (Processing toolbox) apparently due to wrong/old options being used under the hood. The messages I get are:

Oooops! The following output layers could not be open
Grid: /tmp/processing/c0f434bbecc3435aaff4043f25fbb5d6/GRID.tif
Variance: /tmp/processing/4d1dc090b0ba4352a55e78d8e3a38edf/VARIANCE.tif

However, on closer inspection of the log messages the following shows up:

This is with SAGA 2.1, QGIS 2.1.0-Master e04b426. I am having an identical issue on the Windows 7 64bit machine with standalone installer QGIS 2.0.1-2 and OSGEO4W installer.

When I try to run the command in a prompt by replacing SHAPES with POINTS additional options seem to be outdated (FIELD becomes ZFIELD, and so on).

I made a pull request that fixes it, the module changed almost completely since SAGA 2.0.8 (or at least have changed most of the parameters names).

---

• status_id was changed from Open to In Progress

Just updated from master and on Ubuntu the Kriging seems to work with SAGA 2.1. Do you know if the changes are going to make it into one of the 2.0.x Windows installers or will it have to wait until 2.1.x series? Thanks for the quick fix.

You can install an updated version of Processing via the Plugin installer in QGIS 2.0.1.
