[IDV #NDS-367550]: "DataObject doesnt start with OHD" for single WRF output file

> Hardware: Java: home: /Applications/IDV_5.0/jre.bundle/Contents/Home version: 
> 1.7.0_51 j3d:1.6.0-pre9-daily-experimental daily
> Description of problem:

> This is similar to a recent IDV WRF aggregation error I experienced,
> for which I received the following explanation from IDV Support: "These
> wrfout files are in different domain and cann't be aggregated together."
> 
> However, in this case, it is not an aggregation as it is just one WRF
> output file for which the error occurred.  All the other WRF output
> files for the same simulation and domain loaded correctly in IDV.
> Any ideas as to why this one is not loading?

> There was an error loading the data:

> DataObject doesnt start with OHDR


You can try to load this individual file to see if it is working and do not be 
fool by the file name.
