ENGLISH
As I've just told you in my last post, this is the Spanish GRASS
mailling list. I will answer you, but you should use the English one
[1] :)

I think you should find all the info about your question here [2] and
help about imagery commands in [3]

Good luck!

ESPAÑOL
Como acabo de decir en mi último correo, esta es la lista de correo de
GRASS en español. Responderé a tu pregunta, pero deberías utilizar la
lista en inglés [1] :)

Creo que deberías encontrar todas las respuestas a tus preguntas en
[2], e información sobre los comandos de GRASS para el tratamiento de
imágenes en [3].

Buena suerte,
