I tried on Linux with your data and it works ok. I had to set the "height" slider to a low value, though, to see the profile. > By the way, when I type g.region rast3d=[name], it always display: > G3d_readWindow: unable to find [C:/.../PERMANENT/grid3/vox_data50/cellhd]. > ERROR: Invalid region: North must be larger than South Do you have white space in the path to vox_data50/cellhd ? Which winGRASS version do you use? Markus _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
