<DIV>hi ,everybody<BR>Thanks for suggestions. but I still can't process it.</DIV>
<DIV>when I drop -o, the result is the same (only the first four records matched)</DIV>
<DIV>and I fail to find current grib2ctl version (0.9.12.5P33K)</DIV>
<DIV>Can anyone who has this version Email it to me? Thanks in advance!!!</DIV>
<P>I meet GRIBEX by chance from internet, it says GRIBEX is the ECMWF grib de- and encoder. My data is ERA-40. I wonder if it is the ECMWF grib data that GRIB2CTL doesn't work correctly.</P>
<P>Hoping for your suggestions and thanks a lot!!!</P>
