2,750 sq-km at 1mm resolution! thar's yer problem. start with 'g.region rast=dem -p' to reset the region to the bounds of your master map and zoom from there. anything larger than about 50000x50000 rows x cols starts to lag and wants a 64bit OS and lots of hard drive space.. > Well, after about 3 minutes it may move off 0% to > 3%. After 5 or 6 minutes I hit ^C to kill the process. well, on the positive side, it is some proof that grass's raster engine scales rather well and it is just a matter of throwing faster and faster computers at it as they become available. !
