ggrid error

[Valerio Guerra]

Hi all,

I'm trying to use the 'ggrib' utility to slice some big grib2 files into smaller pieces.

I downloaded the sources (ftp://ftp.cpc.ncep.noaa.gov/wd51we/gribw/gribw.tar) to my work dir (/usr/home/valerio) and then:

> tar xvf gribw.tar
> cd /usr/home/valerio/gribw
> make -f gribwlib.make
> cd ggrib
> make -f ggrib.make
> chmod 0755 ggrib

Both the compilation of griw and ggrid completed without apparent errors. But if I run the following:

> ./ggrib bigfile.grib2 slice.grib2 -170.0 45.0 -170.0 70.0

all what I obtain is the error message:

> No records written, skipped 0

and an empty (0 bytes) 'slice.grib2' file.

I tested it both on FreeBSD 6.1 and 6.3.
Any ideas, suggestions?

Thank you.
