[GRASS-user] qgis and grass prosseses error.

Fri Sep 13 07:38:54 PDT 2019

Hi Håvard,

The first thing I would do is to try to remove non-ASCII characters and spaces from your path. Paths like this:

r.external input="C:\Gis\øving 8\klippet transformert.tif"

And the å in your name may be causing problems.

  -k.
