[GRASS-user] Distance edge to edge between ALL the patches of a map

Hi!
I try to calculate all the distances edge to edge between all the polygons
(in a vector map) or patches (in a raster version of the same map) of a
dataset. I cannot use v.distance because it just provides the distance to
the nearest element, and the same applies to r.le.dist for the patches.
Anyone knows a way to do this?
It is a large dataset of +6000 patches/polygons, and the goal of this
calculation is to prepare an input for a connectivity analysis in Conefor
Sensinode.
For example if there would be just four patches the output should look like
this
Patch_A Patch_B Distance(m)
1 2 6141.19
1 3 17192.37
1 4 18426.00
2 3 18768.68
2 4 123.76
3 4 1245.87
Thank you
Javier Godar
