Hi
Thanks Martin but It's not working. With the following command
v.rast.stats -c -e --verbose vector=s...@permanent
raster=se...@permanentcolprefix=stat
I'm getting this error:

Hello,
which GRASS version are you using and on which plattform?
I did it with GRASS 6.4.0RC6 on Linux using the example GRASS dataset and it
worked without problems:
v.rast.stats -e vector=geol...@permanent layer=1 raster=elevat...@permanent
colprefix=new_ percentile=90
and the new

Hello,

I did it with GRASS 6.4.0RC6 on Linux using the example

analysis without using v.rast.stats?
Thanks

please try the latest nightly-build of wingrass64
(http://josef.fsv.cvut.cz/wingrass/grass64/). this issue should be fixed there.

Hello
I have polygon layer which divides my image into several areas all
contiguous. With the same size, I have a raster image. I want to:
- calculate the most frequent value of the raster inside each polygon;
- the maximum and minimum value inside each polygon
How can this be done in GRASS?
Hello,
I think v.rast.stats is what you are looking for
