Hello
Today I have a problem with the module r.patch,
I would assemble miss SRTM, with the command

r.patch input=srtm_35_04@etienne,srtm_35_05@etienne output=asrtm35
--overwrite
But I can not see the result, and I do not understand why ...

GRASS 6.4.0RC6 (ETRS89):~ > g.region -p

Do you have any suggestion?

expand the computational region first:
g.region rast=srtm_35_04@etienne,srtm_35_05@etienne
