In
My suggestion does just that, per pixel calculations. And as it is just
simple GRASS functions, you should have no problem running it (perhaps a
bit of patients depending on your computer).

Dear all,

Just clarifying something, I need to do the estimations focusing on
each pixels, and not for the full map (I was not that clear before).
Also as my raster maps are very large (~50,000x60,000 pixels) maybe R

Sorry, some typo's (but the given code should be ok): set all values <
4/7 quantile to null(), not 0, and you want to calculate the average,
not the sum

Hi Miltinho
I assume you want the mean of the three highest values for each raster
cell? If so, you can do this using another step with r.series
1) If your 7 maps are a1 .. a7:
mapcalc "a1 = 1"; r.mapcalc "a2 = 2"; r.mapcalc "a3 = 3"; r.mapcalc "a4
= 4"; r.mapcalc "a5 = 5"; r.mapcalc "a6 = 6

Hi Milton,
A possible approach could be, for example, to do the following with each
map:
r.stats -1 input=map1 output=cellvaluesmap1
It will create a file containing the cell values for each map. Then you
can read this file into R and average the three highest values. Something
like:
values.m
I have a set of 7 raster maps.
I am able to calculate several stats with these mapas using r.series.
Now I need to calculate the mean of the tree highest values of my 7 maps.
Any idea of how can I do that?
cheers
