Hi,

 I am having problem reading the attached file using MET5 :

 tried : ./bin/plot_data_plane ./NGAC/14Jun/ngac.t00z.a2df42.grb jul.gs
'name="AOTK"; level="A0";'

showed : DEBUG 1: Opening data file: ./NGAC/14Jun/ngac.t00z.a2df42.grb
ERROR  :
ERROR  : GribFile::read() -> file read error ... requested -8 bytes, got -1
ERROR  :

Any help with this.

 Thanks.
 Partha

Hi Partha.

Thank you for sending the grb file.  I was able to reproduce your
error.
Your GRIB file, ngac.t00z.a2df42.grb, is actually a GRIB2 file, but
plot_data_plane thinks it is a GRIB file because of the .grb
extension.
Please rename your file to be ngac.t00z.a2df42.grb2, and you should
then
get a successful run.

Unfortunately, the error you received wasn't very descriptive. We are
planning on updating the error message for this situation in the next
release of MET.

Thanks,
Julie
