r.texture NULL or negative value ERROR (possible r.null problem)

Reported by: khufkens Owned by: grass-dev@…

Description

Concerning r.texture in GRASS 6.3:

Running r.texture on a map after r.null (should have) replaced all NULL values still produces an error indicating a persistent NULL or negative value in the map.

r.category shows no NULL values or negative values but yet they are there for r.texture...

Adding a fixed value to the map with the map calculator or running a running window analysis removes these hidden values and also removes the error.

This traces back to either an error in r.texture or r.null, not sure...

what does r.univar say, before and after r.null?

(run 'g.region rast=yourmap' first)

Ok,

seems that setting g.region makes the error disappear. Sorry, for the inconvencience...
