dear niels, thanks for your answer. unfortunately it didn't solve the problem. i changed the color table into grey and still can't use r.composite. and without that i cannot go for anything else. i really wonder what the problem is! the import finally worked and i do have all the channels in my location... just can't work with them...
maybe somebody else knows what to do, before i have to go for erdas?! rene Am Montag 06 Oktober 2008 09:34:03 schrieb Niels Thevs: > Dear Irene, > > when you display one channel in GRASS, it is displayed by default with a > color scheme ranging form green to yellow or blue to red.
