Hi,
I'd like to know if in grass there is a module to find the shortest cumulative 
cost linkes between raster polygonous from wich r.cost have calculated the 
cost layer.

I try r.drain and r.spreadpath but this commands calculate only the shortest 
cumulative cost from a point and the lower value of the cost or spread layer.

Thank of all
