<div> </div>
<div>thanks for your comments ! <br/>
<br/>
The problems I had before appeared with the grass version of the 31.10, I downloaded the version of the 30.10 and also reinstalled the r.streams.basins, as suggested by Madi. I could not install the remaining r.stream modules. When I tried to do so I got:<br/>
<br/>

</div>
<div> </div>
<div>I run r.basin anyways after deleting all files (as suggested by Markus):<br/>
<em>r.basin map=map@Elevation prefix=o coordinates=-71.10394196,43.9865230801 threshold=19005 dir=C:\\Users\\Andrea\\Basins</em><br/>
<br/>
and I got<br/>

<br/>
I deleted all files before running the r.basin command and I do not know how I can set a –o for the file <o_map_outlet_snap> in my r.basin command ... I do not know what you mean with the "old cruft" ...<br/>
<br/>
I will reinstall grass on Monday or Tuesday with the newest version and will tell you how it goes. <br/>

---> apparently the overwrite fails or you did not specify --o or old<br/>
cruft remained as indicated (please clean it first).<br/>

Mhh, "this should not happen" issue. In a winGRASS installer there<br/>
should not be any version mixture.<br/>
Helli, Martin, any ideas?<br/>

<br/>
No, that should be fine. At time we are doing heavy cleanup in 7, to<br/>
get stuff ready for beta4. Perhaps the installer was autogenerated in<br/>
a bad moment. Please be patient and update it again, for us your<br/>
feedback is very important.<br/>

This is a question for the author of r.basin, I don't know.<br/>

Here is an overview, I hope it is right :-)<br/>
