I'm using GRASS6.4 on a Linux machine.
If I Select i.class from wxpython GUI, I get an empty x0 monitor but, If i
insert i.class in command line it opens a Wxpython Form.
Is this an error or a normal thing?

Hello Markus. Thanks for your answers
As far as I saw, there are no GRASS functions to perform Radiometric
Correction.
There is: i.atcorr.
Regarding i.atcorr I thought that the only thing i.atcorr perfoms is the
atmospheric correction, I mean conversion from TOA (top-of-atmosphere) to
BOA
Relevant for you is this:
- implement/finish linewise ortho-rectification of satellite data
...unfortunately stuck since GRASS 4/5...
Regarding this... According to Lillesand and Kiefer the idea is to correct
geometric distortions of the image.
For instance, the Georrectify module is not

In GRASS 6.3 there was an output vector map option outwalk for
