Hi all,
while using r.drain to trace a flow through a DEM
from a given start coordinate, I found that no
output is produced (empty file with NULLs).
Does anyone have the same experience? Some month
ago I *could* get results...
Little confused,
Markus

Hi all,
I have fixed it for FP maps 
CELL is o.k. as well.
Cheers

Hi all,
r.drain seems to accept all types of raster maps now.
(updated in CVS).
Still a problem is that the drain path becomes an area
sometimes.
I would expect: I regularly get:
(something like this)
| |
| |##|###
\ \##\####
\ \##\#
\---\ \\\\
\ \\
\ \
The "thinning" doesn't take place...
I have a small screenshot here (21kb):

The DEM is 12.5m resolution in DCELL (double FP).
Any help or comment is highly appreciated!
Markus
