%% Moving diffraction patterns
% A MATLAB-based program to generate high energy x-ray diffraction inspired
% line art.
%
%% USAGE
% Enter various parameters in the INPUT section. The meaning of each
% parameter is described below. Then run this script. It will produce a
% plot with the line patterns.

# Miscellaneous Diffraction Image Processing Commands
#  This file defines aliases for several common image processing
#  functions for GE2 diffraction images. This uses ImageMagick
#  program, which is typically available on all Linux and Mac
#  systems - http://www.imagemagick.org/script/index.php
# USAGE:
#  Copy the contents of this file to the bottom of ~/.bashrc
#  Run from terminal: source ~/.bashrc
#  After this, following commands should be available
#  1. Convert TIFF to GE. Saves input.ge2
