[GRASS-windows] Re: Zonal Statistics - min

[Rasmus Borgstrøm]

Hi Markus
 
Yes you're right. Solved the output issue. Thanks! 
 
Next problem is then how to access the minimum value in the stats.txt
file. Can you guide me in a direction or to script examples
(unfortunately I didn't find any in your book)?
I would like have the minimum value used in a r.mapcalc DOS_MODIS =
MODISIMAGE - STATS.TXT(%MIN%)
 
Basically what I am trying to is a Dark Objection Subtraction of a
MODIS timeserie, so if you have ideas for other approaches for this
please let me know. 
 
Best regards, 
Rasmus

You are writing the output to out2 (maybe better call it out2.txt or
even better stats.txt).
It should be in the current directory. The >fields_stats.txt will not
gain
anything since output= is used and not set to output=- (stdout).

I guess you are already there.
