[GRASS-user] [GRASS-dev] execGRASS("r.diversity"): [Error 3] Cannot find path specified \\.grass7\\r.li

Hi Luca,

Thank you very much for your reply.

With the north carolina dataset on image-band "lsat5_1987_10" I get the same error:

(Thu May 22 14:35:33 2014)                                                      
r.diversity input=lsat5_1987_10 at landsat prefix=lsat5_1987_div_ alpha=0.5 size=5

ERROR: Illegal areas disposition
ERROR: Illegal areas disposition
ERROR: Illegal areas disposition
Done.
(Thu May 22 14:35:34 2014) Command finished (0 sec)      

When running "g.region rast=s1993_tm5_rad.1 at test1 -ap", I get the same error:

I upgraded to GRASS GIS 7.1svn (60382), with the same results.

Thank you

please could you make a test with north carolina dataset [0] with a landsat image?
I'm not able to replicate your problem....

could you please run before "g.region rast=s1993_tm5_rad.1 at test1 -ap"

With r.diversity no text file will be created but the outputs are maps...
