Hi Javier

There was a long discussion on that issue this summer. Please have a look at:

Subject: [GRASS-dev] i.segment fails

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
user    0m2.264s
sys    0m0.094s

#

version=7.0.svn
date=2013
revision=55075
build_date=2013-03-07

Thank you very much in advance!

Best regards,

Javier
