[GRASS-user] error: accumulation map does not match with elevation map! (r.basin)

[Helmut Kudrnovsky]

> but when I launch r.basin in a closing section of the basin, I get the
error: "map of accumulations 
> does not match the map of elevations."

r.basin is based upon r.stream.extract and other useful modules.

from the r.stream.extract-manual [1]:

[...]
 If accumulation is given, elevation must be exactly the same map used to
calculate accumulation.
