fast downloading grib is an excellent way to download grib files from
ncep server in a few time, but, there aren't inv (or idx) files in the
gens grib2 directories
(http://www.ftp.ncep.noaa.gov/data/nccf/com/gens/prod/gefs.20070213/00/pgrb2a/)
and in the grib1 directory there are only 10 ens perturbations

How can I download selected records with get_inv.pl and get_grib.pl from
gens grib2 dataset?

Thanks
