Batch processing is a powerful way to automate repetitive tasks. All of the main display and processing functions can be recorded in a batch file and then replayed at a later time. See Batch (§ 2.6.) for more information on batch processing.

Build an image list for processing functions
File to save list in
List of files
Many processing functions require the use of image lists for processing. These lists are saved in a "list file". This Batch Build List utility can be used to easily create such a list file from within a batch file. The first parameter is the name of the list file to save the filenames in and will be used for processing. The second parameter is a list of comma-separated filenames to be included in the list, along with column and row headings.
Sample filename list:
NDVI, 1996, Mean, Jan, dv9601.img, Feb, dv9602.img
