Hi, Greg —
<div>If you get the recent build of GrADS (2.1.a2+) you can use the “-old” option with gribmap downgrade the index version number so it can be used with older versions of GrADS. Have a look at the usage notes in <a href="http://cola.gmu.edu/grads/gadoc/gradutilgribmap.html" target="_blank">http://cola.gmu.edu/grads/gadoc/gradutilgribmap.html</a>. </div>

<div dir="ltr">Hello GrADS Users, Developers and GRIB2 Experts,<br>
<br>
I am running GrADS 2.0.2 which is the last releases that supports the widget options in the scripting language.<br>
<br>
However, when I try to open the GrADS file generated by the latest version of UPP in the WRF-UEMS release from SOO/STRC, the above error message occurs.<br>
<br>
I have tested all the releases of GrADS from this version onward and the error disappears with version 2.1.a2 or higher.<br>
<br>
Does anybody know if there is a work-around for this as I cannot move away from GrADS 2.0.2 until the option to choose the graphics engine is introduced so I can maintain my widget functionality.<br>
<br>
Many thanks.<br>
<br>
Best Regards,<br>
Greg<br>
