The GUI has a hack where commands beginning with "d." are treated specially. If your script name begins with "d.", you may be able to get it to work with your script. Otherwise, the correct way to display the output from a script in the GUI is to add a new command layer. Either way, if the script executes multiple display commands, you need: os.environ['GRASS_PNG_READ'] = 'TRUE' after the first command in order to have subsequent commands render on top of previous commands. Otherwise, each command will clear the image, and you'll only see the result of the last one. -- Glynn Clements <gl...@gclements.plus.com> _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
