grass.mapcalc.Is there any alternative or other way around to get this done?
I am using GRASS 7 in Windows 7.in the MS windows operating system, opened files can't be overwritten (a operating system feature), therefore sum = c + sum isn't work in windows. and AFAIK don't assume that it's always working correctly in linux. ----- best regards Helmut -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Re-Using-a-variable-inside-GRASS-commands-with-Python-code-grass-mapcalc-tp5026161p5026223.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
