[GRASS-user] r.threshold modification

[Bartolomei.Chris]

I'm not sure if this is the correct place to ask for this but can the addon r.threshold have an option to just return the estimated threshold value? As it is written, it returns the the status and value but I can't extract the value in any way i know. It would be nice to have a "-g" argument to return the value for scripting.  Here are my attempts (using an accumulation raster "tmp_accum"):


PY_SCRIPTS="C:/OSGeo4W64/apps/grass/grass-7.2.1/scripts"
GRASS 7.2.1> X1=`python $PY_SCRIPTS/r.threshold.py acc=tmp_accum`

 100%
Suggested threshold is 4182
Done!
GRASS 7.2.1> echo $X1

GRASS 7.2.1> python $PY_SCRIPTS/r.threshold.py acc=tmp_accum > T_test
 100%
Suggested threshold is 4182
Done!
GRASS 7.2.1> cat T_test
GRASS 7.2.1>
GRASS 7.2.1> python $PY_SCRIPTS/r.threshold.py acc=tmp_accum | grep "is" | cut -d\  -f4
 100%
Suggested threshold is 4182
Done!
GRASS 7.2.1>


Am I crazy? I would think one of those methods should get me something usable... (???)

Thanks
