Hello Again, Altough this is a QGIS maillist, maybe someone can give me a hint about this. I want to generate a new raster from the following expression (using r.mapcalculator from GRASS plugin):
A*0.5+B*0.05+C*0.2+D*0.2+E*0.05 All rasters are integer16 geotiff anda have the same resolution. I just get this message: r.mapcalculator ama...@permanent bma...@permanent cma...@permanentdmap=d@permanentema...@permanent= formula=A*0.5+B*0.05+C*0.2+D*0.2+E*0.05 outfile=Erosao r.mapcalc "Erosao" = "( " "a...@permanent" @PERMANENT" *0.5+ " "b...@permanent" @PERMANENT" *0.05+ " "c...@permanent" @PERMANENT" *0.2+ " "d...@permanent" @PERMANENT" *0.2+ " "e...@permanent" @PERMANENT" *0.05)" Illegal filename. Character not allowed. Invalid map Parse error Calculating Erosao. Try expert mode. Finished with error I suspect something very basic is missing but I don´t know what could it be!!
