Yes, same here on Linux. So far so nice. BTW: I have changed r.diversity in SVN and removed the quiet flags to print the output map names rather than only "Done". > However, when running the same code on a larger image (cells=6746328) from my > own location, although it reports Done, no rasters are created. If I subset > the image (cells=1632830) and run it again its works (see # sub2Kruger # code > and results below). So I'm guessing it is a memory issue? ok I simply simulate higher resolution: g.region -p rast=lsat5_1987_10 res=5 -a ... cells: 8137540 and then execute the r.diversity call again. This then calls r.li.simpson --o input=lsat5_1987_10@landsat conf=conf_diversity_5.0 output=lsat5_1987_div__simpson_size_5.0 and it consumes a lot of memory... will check on a bigger machine, perhaps a memory leak.
