Hi Moritz,
I definitely did mean 'g.region -p', sorry for that. I ended up
getting it to work using 'r.mapcalc' after setting the region. I saw
someone online had used it with the simple expression newmap=oldmap.
Then, when I export the newmap it is only of the subset. This small
workaround was easy to set up, but I don't have any idea why it
didn't work in the first place.

In your original mail you gave the following region settings:

my input is:
g.region n=5572425 s=5536865 e=655050 w=626350 res=30
Which would mean that your map is way outside your region as your n and
s values are an order of magnitude higher then those of the map.
However, I have encountered a new problem. On one of my ETM+ images,
the subset is returned as an empty raster. The process runs fine on
the other ETM+ image from one year earlier but for some reason, the
subset from the scene one year later has a min and max data range of
'NULL'. This range appears to be constant across all the other
scenes, so is there a way for me to quickly edit this scene so it has
the correct data?
Again, I would suspect region issues.
Moritz
