I am currently using UVCDAT gui, v2.8, on Edison.
I loaded a variable from a netcdf file. Then I realized that I needed another variable, so I regenerated the netcdf file with the extra variable. However, when I go into the 'load variable' window, I select the file again but it doesn't update the variable list. I presume the list is cached and not refreshed. If I rename the netcdf file I can load the new variable.
Is there a better way to refresh the list of variables?
