Joaquim,

This is because the NetCDF driver represents each array object
in the .nc file as a subdataset.  So the "main" file is just a dummy
used to list the subdataset names.

However, I think I asked Denis Nadeau to look into treating single-array
files at the "root" level to avoid this confusion.  I'm not sure if that
was done.  If so, you could update to GDAL CVS, otherwise we need to wait
for Denis.

In the meaintime you can access 'NETCDF:"vs_new.nc":z' as the dataset name.

Best regards,
