I am trying to use r.stream.basins to delineate multiple watersheds upstream of 
water sampling points. From the manual page it appears that you can input a 
vector file with multiple stream outlet points under the command points= 
however I can't make that work. I get the error "ERROR: Only one outlet 
definition is allowed". 

The manual states that the "Every point shall have his own unique category." 
which I assume is the case for a vector file of points but perhaps I'm missing 
something. I have edited the points to make sure that each point overlays the 
stream on the stream direction map. My stream and direction maps are both 
output from r.watershed. 

Can anyone tell me what I'm doing wrong here? I'm using GRASS 7.0 on Mac OSX 
10.7.5. 

Thanks, 

Jens Hegg
