Hi Radim,

I just tested one of the available modules on a local DEM file, and here is there error message that appeared when I ran it:

 Cannot start module r.slope.aspect
command: /usr/local/Cellar/grass/6.4.2/grass-6.4.2/bin/r.slope.aspect --interface-description

ERROR: GISRC - variable not set 

Note that I am running a version of grass installed locally, not from the application that William makes available.

Regards,
John
