Hi Wesley and Jeff,<br><br>Thanks for your help. Tweaking the xdef/ydef fixed it!<br><br>-Jacob<br><br><div class="gmail_quote">On Mon, Sep 20, 2010 at 3:59 PM, Wesley Ebisuzaki <span dir="ltr"><<a href="mailto:Wesley.Ebisuzaki@noaa.gov">Wesley.Ebisuzaki@noaa.gov</a>></span> wrote:<br>

<br>
The program <a href="http://grib2ctl.pl" target="_blank">grib2ctl.pl</a> uses a very simple method for determine the<br>
display grid. To see the corners,<br>
you'll have to tweek the definition of the display grid. Look for the<br>
"xdef" and "ydef" lines in the<br>
ctl file and change it to something that you like better. There is no<br>
"magic" in the numbers;<br>
you can change the nx/ny, x0/y0 and dx/dy.<br>
<br>
xdef nx linear x0 dx x0, dx are in degrees<br>
