Hello! I am trying to run r.basin for some analysis and it start promising but it end badly:
##########
r.basin.py map=dem_fill@harta prefix=a easting=491896.20 northing=659955.69 threshold=900
Removing raster
Raster map not found
nothing removed
SECTION 1a (of 5): Initiating Memory.
SECTION 1b (of 5): Determining Offmap Flow.
SECTION 2: A * Search.
SECTION 3: Accumulating Surface Flow with SFD.
SECTION 4: Watershed determination.
SECTION 5: Closing Maps.
Writing out only positive flow accumulation values.
Cells with a likely underestimate for flow accumulation can no longer be identified.

I must mention that I have Grass64 installed from https://launchpad.net/~grass/+archive/grass-stable on Ubuntu Maverick and all dependencies needed ( I have managed to run separately almost every command but I have in total 22 basins)
Please could someone point me in the right direction ?

Hi,
2011/8/1 Rosca Bogdan <roscao@gmail.com>:
grass\.run\_command\('r\.stream\.extract', elevation =r_elevation, accumulation = r_accumulation, threshold = th,
d8cut = 'infinity', mexp = 0, stream_rast = r_stream_e,
stream_vect = v_stream_e, direction = r_drainage_e, flags
='-o')
replace `flags = '-o'` with `overwrite = True`

There are probably more problems further down with e.g. flags = '-v'
in lines 249 and 254. Also, some of the printed messages should use
grass.message() to avoid spoiling the output written to stdout.
