[GRASS-user] Re: Calculating standard error of many maps?

[Martin Wegmann]

hello Rainer, 

just look at r.series.

If the naming of the files is similar you can try something like:

r.series input="`g.mlist pattern='insitu_data.*' sep=,`"   
output=insitu_data.stddev method=stddev

regards, Martin
