[GRASS-dev] i.segment: Invalid region id -1

[Nikos Alexandris]

Hi,

I am trying to (re-)segment a group of high resolution multi-spectral bands 
(QuickBird2). I work with

version=7.0.svn
date=2013
revision=58327M
build_date=2013-11-29

and use a seed map (result from the Panchromatic band) and, unfortunately, I 
got twice the same error message

--%<---
i.segment msx out=segments_msx_t0.02 threshold=0.02 minsize=4 
seed=segments_pan_t0.02 memory=10000 iterations=1000                                                                                                             

0..5..10..15..20..25..30..35..40..45..50..55..60..65..70..75..80..85..90..95..0..5..10..15..20..25..ERROR: 
Invalid region id -1
--->%--

The region I am working in is indeed large,

nsres:      0.6
ewres:      0.6
rows:       12384
cols:       12303
cells:      152360352

but (almost) the same extents didn't cause any errors in another, very 
similar, segmentation attempt (again with QuickBird2 data). What should I look 
after?

Thanks, N
