g.region error

[Shawn Boeser]

Thanks Bill for your first reponse.  I'm running the SWAT program
which was developed with a GRASS interface.  One of the SWAT developers
told me to try UTM or Albers for my projection.

I'm converting Arc/Info
vectors to GRIDS, then converting the GRID to an ascii file.  I've rearranged
the ascii header to conform to GRASS and then converted it to a grass raster
using r.in.ascii.

When I run my swat program it calls r.stats.  Then I get the following errors
depending on which projection I've defined in the location.

If I use the UTM projection I get this error:

    >WARNING: G_set_window(): North must be larger than South

r.stats still works despite the error but, will bomb out later.

If I use the Albers projection I get this error:

   >0 WARNING: G_set_window(): North must be larger than South
   >sh: /erdas/grass4.1/mapgen/bin/proj: not found
   >WARNING: Unknown lat and long, either projection is not correct
         or mapgen proj function is not working

and r.stats does not work.

Here is my g.region -p for the UTM projection:

projection: 1 (UTM)
zone:       17
north:      2278984.59124088
south:      2264863.40875912
east:       1024728.93333333
west:       1012293.06666667
nsres:      101.59124088
ewres:      101.93333333
rows:       139
cols:       122

Here is my g.region -p for Albers:

projection: 99 (Albers Equal Area)
zone:       0
north:      2313216
south:      2262345
east:       1030049
west:       953302
nsres:      98.97081712
ewres:      100.06127771
rows:       514
cols:       767

Any help will be appreciated.  I can't get on with my project until
I get beyond this error.
