Hi, I have a multitude of image files that I am attempting to apply a decision tree to. I have created the decision tree to analyze the images, but am looking for a way to apply the decision tree to my images and retrieve the output. In envi I can do this one image at a time simply through the envi interface, but I was wondering if anyone could provide me with the commands for IDL that could access the bands my images have in envi and then apply the band math to the images automatically. If anyone knew the commands or could provide me with a minor script that would be thankful. Maybe this belongs in the envi forums.
