Hi Mohamed and Markus Mohamed, thanks for your reply, I will wait for a solution within GRASS :-)
Markus, thanks for your reply,. Sorry but I disagree a tiny bit, because is expected that between a source and target I will find a solution with the Least Cost path. Do you think that is there any situation where a least cost between source and target will not be found? Maybe if other software provide the soluction, although is not the bestest option, I prefere receive one complete output than a broken one.
