Dear users:

I'm trying to open a grib2 file with Grads but I've found problems in my
way.

I have been able to create a descriptor file with the function
g2ctl.plusing the following sentence:

perl g2ctl.pl -0 pgbhnl.gdas.2006020112.grb2 >
pgbhnl.gdas.2006020112_grib2.ctl

but, when I've tried to create the index file with the function gribmap, I
have obtained the following error message:

gribmap -i pgbhnl.gdas.2006020112_grib2.ctl
Open Error:  Data file type invalid
  --> The invalid description file record is:
  --> dtype grb2
  The data file was not opened.

This is part of the descriptor file obtained:

dset ^pgbhnl.gdas.2006020112.grb2
index ^pgbhnl.gdas.2006020112.grb2.idx

Does someone know what is the problem? What is wrong in my procedure? and
how can I create the index file?

Thank you very much in advance for your help.

Sincerely:
Javier Pe?a
