I've been trying to run a r.texture filter on a map but I constantly get the error:
ERROR: Negative or no data pixel found. This module is not yet able to
process no data holes in a map, please fill with r.fillnulls or
However, I ran r.null to set all NULL values to 0 and r.categories also showed no negative values afterwards.
What could be the cause of this error.
I also rescaled the categories between 0 and 100.
After all this the ERROR is still their.
Furthermore, If I run a 3x3 r.neighbourhood average moving window analysis on this map, r.texture runs fine on the result of r.neighbourhood.
I really don't know what causes this inconsistent behaviour. Any ideas what causes this error?
