thanks Glynn, here is what I am doing. After I type the command two new windows open up: one a grid with a faint outline of the input raster maps, the other what I consider to be a navigation window, to help displaying on the grid the area to be edited. I want to extend the track21_raster map line, a walking track. So I click on the cell nearest to the last colored cell in the grid and enter the two category values I have, in the bottom grid display boxes: one called value (I enter a 1, the track segment value), the other aspect (I enter the elevation, 640) then press enter. (There is a third box called also Value, which I leave blank as I don't know what to place there!). A new whitish cell is created. I repeat the process for a few cells then save, but nothing is saved. The output map is identical to the input. The following is displayed in the terminal: WARNING: Raster map <tmp.d.rast.edit> not found WARNING: <tmp.d.rast.edit> nothing removed Is it possible that the new cells are painted in white therefore invisible when seen in the display? I have not found a way to change their color. Any further help you can give will be most welcome. By the way I am on GRASS 6.3 and Ubuntu 8.04.
