[GRASS-dev] i.segment fails

[Javier Martínez-López]

Dear list,

I am trying to run the i.segment function but I always get the same
error during the first pass: 'invalid region id 0'. What does it mean?
can it be solved? I have read some e-mails about this problem but have
found no solution yet. Trying with different thresholds or changing
the memory limit does not work.

My output:

GRASS 7.0.svn (global_MW):/home/user/HRI/Variables > time i.segment
gr=segm out=virunga_segm_0.5 thre=0.5 mins=15 memory=50000
Pass 1:
ERROR: Invalid region id 0

real    0m2.364s

Thank you very much in advance!

Best regards,
