[GRASS-user] Problem running r.terraflow

[Margherita Di Leo]

Hi all,

i have a problem using Grass 6.5 with a raster elevation map running the 
command 'r.terraflow'.
I need to obtain the flow accumulation with MFD.
The error is the following:

'cell file dem resolution differs from current region'.

I ran the command 'g.region -ap rast=dem' and this is the result:

projection: 1 (UTM)
zone:       33
datum:      wgs84
ellipsoid:  wgs84

south:      6541497.53951495

ewres:      10
rows:       10959
cols:       14931
cells:      163628829

with 'r.info' the result is:

Please can you help me? Any idea about what's wrong?
Sorry if my question is trivial.
