I'm trying to do pattern detection of an STRDS (hourly precipitation 
from radar images) with a cycle of 3 hrs. The last step, 
t.rast.accdetect errors as follows (after finishing to create the 
pattern rasters):

Traceback (most recent call last):

sqlite3.IntegrityError: UNIQUE constraint failed: raster_base.id

If I understand correctly, the 'id' (Primary Key) in raster_base is 
created from the raster name and mapset. So why am I getting this 
"UNIQUE constraint failed" error? Any tips?

Thanks, Micha
