It works... I'm sorry, it was a problem with my vector. It gave me errors because it wasn't correctly dissolved... Thanks anyway, for the hint.
I will open another post for the other question: why is the creation of new vectors in v.categories, v.dissolve, and similar commands needed? Couldn't it be an option, so one could overwrite the original vector? I imagine it shouldn't be difficult to realize it... 2008/8/9 Moritz Lennert <[EMAIL PROTECTED]>: > On 08/08/08 19:43, G.
