Austin, I am a little confused by what is going on. I can see from your support ticket that you have data loaded so you should be able to view one or more fields. If you are having trouble, these videos may help http://goo.gl/n0Frpb. Also, the IDV has no capability to export to grib. You can export to netCDF via the Dashboard, Displays Tab, File -> Save menu item Best, Unidata IDV Support > Full Name: austin dooley > Email Address: address@hidden > Organization: self > Package Version: 4.1 build date:2013-08-02 18:38 UTC > Operating System: Windows 7 > Hardware: Java: home: C:\Program Files\IDV_4.1\jre version: 1.6.0_43 > j3d:1.5.2 fcs (build4) > Description of problem: Creating display: Image Display > No data selected > > I've clicked on the grib2 file but the system says no data selected.
