I used r.watershed to get the streams channels and now I am looking for an<br>
automatic way to dismiss the part of the network above the points of<br>
interest for my application.<br>
<br>
Is that any tool to do that with GRASS?<br>

Yup. Make a mask (see r.mask) and use that to either select the subbasin<br>
you want or to remove the portion you don't want.<br>
