I installed Xubuntu on my notebook with GRASS6.2.2 (from the repository) and I tested spearfish.sh with good results!! Thank you very much for your suggestions and support!!<br><br>PS: I saw that elevation.dem_depth is the raster with the water depths in each cell. How can I see the values of these water depths?<br><br><b><i>Hamish <hamish_b@yahoo.com></i></b> ha scritto:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> roberto caselli wrote:<br>> I have a Notebook and a PC:<br>> <br>> The Notebook is an Acer Travelmate with 512MByte Ram, windows Vista<br>> and cygwin.
