Hi everyone,
I have a problem on output raster map of cumulative cost when running the r.cost.rast algorithm. the resolution of Output raster is 5 m. Or the resolution of my input raster ( cost raster and raster of starting points) is 1 m.
I cannot figure out how the resolution can be diffrent form input to output
Thanks,

The resolution doesn't depend on the input, rather the computational extent
and resolution must be set using g.region module:
http://grass.osgeo.org/grass70/manuals/g.region.html
so for example if you want to set the extent and resolution based on a
raster map 'my_input_raster' you use (-p is for printing resulting region):
g.region raster=my_input_raster -p

Anna
