Before I supply a full script with external data, I wonder if I can make synthetic data to debug/recreate this more easily. I see that I can do "r.mapcalc 'x = 42'" to create a new vector raster with 1 point. Is there some easy method to create a 2D raster within grass? Or should I make a simple ASCII CSV file and read that in? If I can recreate the behavior with a small hand-made data set I think it would help me figure out what is wrong with the data.

Thanks,

  -k.
