[Qgis-user] Any tutorial on how to add grass modules to sextante-QGIS?

[S. Koukoulas (lists)]

ok, I have created two files (attached), based on the guide provided and
copied them to the description folder. I reloaded the sextante plugin
and could see the two new commands in GRASS, raster(r.*) menu.

However, when I run them, I receive an error message saying that it
Could not load layer: ...tempdata/grassvaltonullc3....tif and to check
the log file for more (but there isn't anything logged as an error).

The commands run smoothly in Grass so this does not seem to be the
problem. The only thing I could see is that *the r.null command does not
take an output file argument*... It changes the input file. But sextante
requires an output in order to export it from grass to tif.
Any ideas?

cheers,
sotiris
