I am having some problems getting something useful out of
r.terraflow.short.
what version of GRASS?
what OS do you use?
I have a fairly large rasta (Data type CELL, rows: 12,500
columns: 6,250 total: 78125000). My final objective is to
get a watershed basin limits and river network.
you probably want r.watershed to get full watershed basins, r.terraflow
basins are a slightly different creature. also, you'll want to use
r.watershed from a newer 6.4.0RC release. the older versions are
horribly slow. see the help page for hints on extracting river networks.
Since the rasta is large and in integer for I have tried using
r.terraflow.short. However the command finished in 0 sec and
no outputs are generated. The message is as follows:
....
r.terraflow.short -s --overwrite --verbose
elevation=431112@Imatong filled=1fld direction=1dir
swatershed=1snk accumulation=1acc tci=1tci memory=100
stats=3stats.out
....
file 3stats.out exists - renaming.

please try with 6.4.0RC5, there was a recently fixed bug which may have
been corrupting the STREAM_DIR option. (?)
