Hi Jarek! I think that, with Horton and Strahler, it would be useful also Hack stream order, it is very nice because assigns value 1 to the main channel and so it is simple to achieve the main channel lenght. (Please see http://jgrass.wiki.software.bz.it/jgrass/Horton_Machine#head-f736e2e27c29

These white spots in the voronoi vector may be the cause. But i ran the voronoi module on the "archsites" vector of the Spearfish60 dataset and its runs fine. The cmd was v.voronoi input="archsites" output="arch_voronoi" The only difference is that the region of archsites has got less points (a
