Well, thanks, but that's the part that I already knew. Sorry if I
formulated my problem badly.
What you describe will give me an output raster file which is in fact an
index referring to my input series of raster files, right? Now what I
want to do is use this result, the index raster, to get values from
comparable but different raster series, e.g. different bands of the same
time series. My problem is not how to define the series or have them as
input using g.mlist, I know how to do that. My problem is that I want to
do e.g. r.series.fromindex input=$series_red index=$output_of_min_x.
