The program reads and dislays images in the Kevex 8000 .img file format. The analysis proceeds as the program prompts the user to select points on the Kikuchi bands to index the pattern. The output is displayed on the screen and the user can select the solution that makes most sense, this is then saved in both long format and as orientataion matrices and pattern numbers.
