GRIB conversion

[Huopo Chen]

I have the same problem as you before,but when I input the following code the problem disappeared.
You can try it.  
 gribmap -e -i Y48659*.ctl

Hello All,
    I have coverted my grib file to ctl file, however there is one problem,  the index file is not generating......here is what I type and what was responded:
       
           grib2ctl.pl Y48659* > Y48659*.ctl      : (everything was fine until I type the next line)
           gribmap -i Y48659*.ctl -0
            Error in the grid specification for GRIB grid type 29/30
            Grid scaling must indicate 2 2.5 x 2.5 grid
            Grid size must be 144 x 73
            Grid must go from 0 to 357.5 and -90 to 90

could someone help me with this if I can get the index file to generate Grads will do the rest......
                                            thanks 
                                               DANNY

I use this script instead of 'draw title'.

* This is an alternative to the 'draw title' command in GrADS.
* Font characteristics are controlled by five script variables:
* height, width, color, thickness, and font number.
* The sole argument is a string of any length which may
