Comment(by mmetz):

 From the dev ml, Oct 11 2011, Claudine Gravel Miguel:

 "I think I've found what I thought it wasn't working. I reran the whole
 thing on both UTM and conical and when looking at a big region, it seemed
 like it wasn't working, but as soon as I zoom the window on the 'center'
 point and I recalibrate the colors of the r-walk output, then the paths
 appear to be fine, on both locations. I also ran the whole thing in both
 6.4.2 and 7 and both works fine. I wonder if the problem you had is the
 same, Michael, or if it was different.

 I think that te reason why I thought the circle around the center point
 was wrong is because I was comparing it to r.walk in lat long, which was
 following very closely the results found in r.cost (following the
 valleys), which, I know realize, were the wrong type of outcome.

 So, I guess my part of the problem is resolved. Thanks for your help!"

 Close ticket?
