[GRASS-user] g7 svn58117 r.random ERROR: There aren't [n] non-NULL cells in the current region
Hi all, I'm having a small issue generating random points across a map with GRASS 7 svn rev. 58117. When running r.random I get the following error: r.random land_cover_classification@PERMANENTvector_output=accuracy_assessment_random n=1000 Collecting Stats... ERROR: There aren't [1000] non-NULL cells in the current region (Mon Oct 28 10:51:22 2013) Command finished (1 min 3 sec) My region is: g.region -p projection: 99 (Lambert Conformal Conic) zone: 0 datum: nad83 ellipsoid: grs80 north: 448953.41346712 south: 238997.2442541 west: 673974.37382019 east: 890151.92813758 nsres: 3.27959152 ewres: 3.27959152 rows: 64019 cols: 65916 cells: 4219876404 r.stats for the land cover map: r.stats -c input=land_cover_classification@PERMANENT 1 89740438 2 767001523 3 824629190 4 76402738 5 331550200 * 2130552315 (Mon Oct 28 10:57:07 2013) Command finished (1 min 11 sec) So, there are plenty of non-null cells in the region.

Thanks, Hamish. My machine is 64 bit.
