[gradsusr] problem with g2ctl

[Geeta Geeta]

Hi, 
I have grib2 files which I want to plot using Grads. 
 
 
bash-3.2# ~/g2ctl -0  fnl_20130522_00_00 >temp.ctl
bash-3.2# gribmap -0  -i temp.ctl
Open Error:  Data file type invalid
  --> The invalid description file record is:
  --> dtype grib2
 
  The data file was not opened.
File name is:  temp.ctl
bash-3.2#

I donot know whats the problem ???
Can somebody suggest????
