Dear All,
I am experiencing problems importing ESRI GRIDS into GRASS 6.4.0. I has
worked well before. Now when import (r.in.gdal) the the rasters the only
warning I get is:
WARNING: Fixing subtle input data rounding error of north boundary
(1.19996e-10>2.77778e-07)
but when I look at the rasters afterwards, they contain only nulls.
I checked the grids:
gdalinfo A1B_2020_2049_cccma_cgcm3_1_t63_prec_2

The grids display flawlessly in QGIS. Also converting them to *.asc or *.tif
using gdal_translate did not help to resolve the import problem into GRASS.
If any one has a hint where the problem could be, I would greatly appreciate
it.
Thanks
