I am running a least cost path analysis combining r.cost and r.drain.<br>
But on some cases, when the least cost path between source and target<br>
reach the border of my map, r.drain stop on that position, and target<br>
point isn´t reached. Running on other softwares the algorithms the<br>
source and target is connected using edges without problem.<br>
<br>
Any hint are welcome.<br>

Merry Xmas<br>
