[AWIPS #LJS-519939]: AWIPS Functionality and Imaging Glitch

> Dear AWIPS team,
> 
> Our IT folks at the University of Kansas recently reimaged our Linux lab and 
> installed the most recent version of AWIPS Cave (v 18.2.1-6). We had 
> previously been using a build from prior to 2019 and IT team claims the new 
> install was straightforward for our version of RedHat.
> 
> I was test driving functionality today and noticed some quirky behaviors when 
> attempting to load products as images. Specifically, the color bar for images 
> does not necessarily match the expected values for the field when plotted as 
> contours or using the sampling tool. I've tried different sources/datasets 
> and the issue seems to be variable specific.
> 
> A few images that show off the inconsistency are in a Google Drive folder. 
> Should it be helpful, I'm also including a link to the installation summary 
> from the about AWIPS menu.

Hello,

Thanks for reaching out and I'm sorry you are having issues. Can you tell me 
the username that CAVE is being run as and what the name of the computer is? I 
went to load the same images that you did and for images 1 and 2 our contours 
looked the same, but the image was very different. I'm thinking there's a 
possibility where you all made a user override at some point of some of the 
display properties (while these are user changes, the files reside on the EDEX 
side). I can look into this if I know your username and machine name.

Just to confirm a few things - were you loading these products from the Volume 
Browser or Product Browser? Are you running Redhat7? 

Thanks,

Tiffany Meyer
