Description

This program is designed to make modifications to various objects and groups found in ISIS cube labels, but a .pvl file can also be used. When a PVL is used, an interim processing file will be created, which you can later remove. Using either file type, you can add/delete or modify keywords in a group (e.g.: 2, 3, 5), or add or remove entire groups (e.g.: 1, 6) within the labels. For simplicity's sake, use a template (e.g.: 4) to modify labels, as this makes it unnecessary to run the program multiple times when adding new groups. Examples can be found at the end of this document.
