[GRASS-user] Python script

GRASS GRASS user

Hi,
  I'm trying to use r.stats via the python shell inside GRASS but I'm
getting an error that I do not know how to solve. The code I'm using is
this:

grass.run_command('r.stats',input=inp,output='D:\\CropScape\\2012_cdls\\AZ.c
sv',flags = 'ani')

I already tried the following variables for input:

inp=['AZ','COUNTIES']
inp=['AZ@PERMANENT ','COUNTIES@PERMANENT']
inp=['D:\\CropScape\\2012_cdls\\AZ.tif',
'D:\\CropScape\\Counties\\COUNTIES.tif']

Every time I get the same error: " GRASS_INFO_ERROR(1444,1): Raster map
<D:\CropScape\2012_cdls\AZ.tif> not found"

Any idea of what could be?

Thanks,
  Pedro

Either of these should work, provided that you actually have maps with
those names in the PERMANENT mapset.

inp=['D:\\CropScape\\2012_cdls\\AZ.tif',
'D:\\CropScape\\Counties\\COUNTIES.tif']

The inputs must be map names, not filenames.

Have you actually created the maps? You cannot use an image file as a
map without first either importing it (with e.g. r.in.gdal) or linking
it (with r.external).
