HI LIST!

I have a five years  time serie of NDVI, and i need to obtain the average
value of some polygons in a vector shape named "buffer_xime4", Im trying to
use v.rast.stats into a for cicle as follows:

contador=1
for map in `g.list rast pat=MOD13*A2010*NDVI`
do
v.rast.stats -c map=buffer_xime4 raster=$map column_prefix=$contador
method=average
let contador=contador+1
done

But grass (GRASS GIS 7.0.4) returns this error.
