Hi Andrés,
Unfortunately I can't say nothing useful about this particular error
but, for what it's worth, the GRASS GIS algorithms r.cost and r.drain
that can be easily accessed via the GRASS GIS plugin, works pretty fine
with very good results.
Cheers,
Lluís

Hi!
I am conducting a study of territories exploitation of archaeological
sites.
To do this I need to create a layer of accumulated cost isotropic,
taking as a starting point to study the site.
For the creation of the layer of costs, I use a layer of fricion
created from a DEM as a starting point and a raster layer of site. The
layer of site has been rasterized from a vector layer in which the
site has been applied to a value of 1.
We appreciate indicate me as I can do with QGIS. I used the acululado
cost (isotropic) SAGA process, but I get the following error:
Oooops! The following output layers could not be open
·Accumulated Cost:
C:\DOCUME~1\deportes\CONFIG~1\Temp\processing\aefc4bf43b194e51acdfd655b5c6fc31\ACCCOST.tif
·Closest Point:
C:\DOCUME~1\deportes\CONFIG~1\Temp\processing\0433fdc33f93400c85b524e9cc2dd749\CLOSESTPT.tif
The above files could not be opened, which probably indicates that
they were not correctly produced by the executed algorithm
Checking the log information might help you see why those layers were
not created as expected
This algorithm requires SAGA to be run. A test to check if SAGA is
correctly installed and configured in your system has been performed,
with the following result:
/SAGA seems to be correctly installed and configured./
The problem pudede be that the process needs a point of arrival and
not starting?
Best Regards
Andres Ocaña
