[GRASS-user] problems r.walk region

[Luis Miguel Royo Pérez]

Hi everyone,

I'm getting troubles to run r.walk. If I run r.walk in this *region*:

    projection: 3 (Latitud - Longitud.)
    zone:       0
    datum:      wgs84
    ellipsoid:  wgs84
    north:      33:39:03N
    south:      29:16:03N
    west:       33:54:48E
    east:       40:34:24E
    nsres:      0:00:03
    ewres:      0:00:03
    rows:       5260
    cols:       7992
    cells:      42037920

the algorithm runs fine.

But _isn't the region_ I need analyze, when I *change* into this other one:

    projection: 3 (Latitud - Longitud.)
    zone:       0
    datum:      wgs84
    ellipsoid:  wgs84
    north:      37:21:17.568N
    south:      25:06:44.82N
    west:       31:46:15.96E
    east:       43:23:24.576E
    nsres:      0:00:08.999949
    ewres:      0:00:08.999272
    rows:       4897
    cols:       4648
    cells:      22761256

The algorthym *stucks* in the /Calculating cost/ step. It's a widest 
area, in exchange the number of cells has been reduce a lot.

I'm running _GRASS 6.4.3 on Ubuntu 12.04_. I thougth this could be due 
to a lack of RAM???.

Can anyone help me??

Thanks a lot.

Luis.
