I'll check my revision. Thanks for the info. Also, I found that thinning the stream raster from r.watershed and converting it to vector doesn't really work well. When there are clumps of raster cells, flow directions get messed up. I tried your r.stream.extract to extract stream lines and its output makes much more sense. It would be great if this module also outputs unique stream "network" numbers.
Thanks.
