[GRASS-user] Using v.distance between two identical layers...

[devaux at supagro.inra.fr]

Hi,
do you know if it's possible to use v.distance command when "for" and  
"to" layers are
the same layer ?
I have a layer describing ecological areas of interest and I want to  
qualify spatial
relation between all patches. I want to identify and calculate  
shortest relation between
all my patches boundaries.

How can I do as v.distance command doesn't have any option like :  
eliminate identical
objects from the "from" and "to" layer ?

I'd like to use this particular command because of the option that  
create lines between
nearest objects.

Thanks

Nicolas
