[GRASS-user] r.stream.order (GRASS 6), Hack, fails at some confluences

[Hanan Karam]

Hi everyone, 

Does anyone have experience with r.stream.order failing at some stream confluences for Hack ordering, such that the rest of stream network upstream gets assigned an order of -1?     
When I re-run the algorithm starting just upstream of the confluence, it works.    I have seen many instances of this type of failure.  Please let me know if you have any ideas on why it might be happening and what I can about it.

Thank you very much, 
Hanan
