This error message is now hopefully more useful in 6.4.svn (i.e. 6.4.3 in the very near future). Would you mind to upgrade to the nightly snapshot?: http://wingrass.fsv.cvut.cz/grass64/ and try again? As a bonus it includes many more bugfixes. We need to know if the better error message is triggered or not. > I understand that this is due to the standard memory installation of 64mb of > RAM allocation. While GRASS may even run with 64MB RAM, you likely mean 64bit CPU (rather than 32bit). To some extent, GRASS 6 offers large file support for raster data while GRASS 7 aims at complete large file support for raster and vector data on 32bit architectures. > How can i overcome this limitation.I also need to solve this > on my Ubuntu 12.04 install To not leave you in the dark: the computation region (http://grass.osgeo.org/wiki/Computational_region) will be either to large or have too many raster cells active (too high resolution). So, in the first place check the output of g.region -p However, please make the winGRASS test for us first, thanks!
