Thanks for getting back to me.
I am using 6.2.1, and g.region -p gives the info:
projection: 1 (UTM)
I'm trying to run with the resolution of 3m, but when I change it to 30m,
there isn't a problem. Using much smaller regions doesn't seem to have
this problem. So is the file just too large at too small of a resolution?
I'll try to run Spearfish and let you know.
