Hi Glynn,
Thank you so much for your response.
I thought the easiest thing (since my python skills are limited) would be to
copy the contents of "%APPDATA%\GRASS7" to
"D:/Bands_processed1/.grass7/r.li", which I have done. I then created a
configuration file using r.li.setup in this directory as follows:
"conf_diversity_5.0"
SAMPLINGFRAME 0|0|1|1
SAMPLEAREA -1|-1|0.010526315789473684|0.009487666034155597
MOVINGWINDOW
Now when running the code, I get the following error:
execGRASS("r.diversity",flags="overwrite",
parameters=list(input="s1993_tm5_rad.1", prefix="s1993_tm5_rad_divers.1",
alpha=0.5, size=5))
ERROR: Illegal areas disposition
ERROR: Illegal areas disposition
ERROR: Illegal areas disposition
ERROR: Illegal areas disposition
All works are terminated
The sample area didn't look right to me as my bounding area is, Top: 7389715
| Left: 272685 | Right: 506715 | Bottom: 7179985 in UTM Zone 36S. So, I
change the conf_diversity_5.0 file manually but I still get the same error
Any suggestions would be appreciated.
Thanks again
Sandra

r.diversity.py is broken on Windows:
home = os.path.expanduser('~')
rlidir = os.path.join(home, '.grass7', 'r.li')
The script tries to create an r.li subdirectory, but fails because the
parent directory doesn't exist.
$HOME/.grass7 is correct for Unix, but on Windows it's %APPDATA%\GRASS7.
From lib/init/grass.py:
# configuration directory
grass_env_file = None # see check_shell()
if sys.platform == 'win32':
grass_config_dirname = "GRASS7"
grass_config_dir = os.path.join(os.getenv('APPDATA'),
grass_config_dirname)
else:
grass_config_dirname = ".grass7"
grass_config_dir = os.path.join(os.getenv('HOME'),
grass_config_dirname)
