It works fine on my machine. Mac OS X, compilied addon and compilied GRASS from scratch. The strahler output also looks sensable. I do have a question, though. Say I have my own delineated streams with another method, but in raster format- will this still work? And is there an easy way to a vector out of a raster stream network?
