[GRASS-user] [GRASSLIST:1112] r.flow barrier bug?

[Jonathan Greenberg]

I can't seem to get r.flow working with a 1/0 barrier file I made from
r.mapcalc.  It outputs the vector fine without the barrier file, but when I
use a barrier file it doesn't output anything.

The output is as follows (note that it never creates a set of flowlines):

***

Opening output files...
The vector 'streams' already exists and will be overwritten.
done.
Allocating memory: elevation, aspect, barrier, flowline header, e/w
distances, quantization tolerances.
Reading input files: elevation...
, barrier

***

Ideas?
