Soeren,

   Current mapset is 'analyses':

> g.mapset -p
analyses

   Some maps might be in other mapsets so ...

> g.mapsets -p
Accessible mapsets:
analyses PERMANENT features soils topography precipitation

which is all the mapsets in the location.

   The file, itzi-param.txt, contains:

[time]
duration = 2:00:00
record_step = 00:05:00

[input]
dem = be_cropped at topography
friction = n
rain = rain

[output]
prefix = pop
values = h, wse, v, vdir, boundaries

[statistics]
stats_file = pop.csv

   And this is the traceback:

   Please suggest what I should try modifying.
