I'm unable to remove or make transparent the black backgrounds that come with my hyperspectral images, making processing and analysis more difficult. I have attempted setting the "zero" or other black background values as invisible, but I actually can't access metadata editing. When I click on "edit metadata", a message with "Parameter; averagepixeldisp, ";averagepixeldisp" is not a valid IDL variable name." shows up and the program will often close itself after.
