CrystalDiffract works with CrystalMaker, reading from saved crystal files to simulate and display powder diffraction patterns on screen. You can drag-and-drop a crystal file into CrystalDiffract, or use CrystalMaker's Transform > Diffraction Pattern > Powder command to obtain a diffraction pattern for any displayed crystal structure.
Diffraction patterns can be displayed as traditional greyscale "films", or as diffractometer traces (graphs of intensity versus two-theta, d-spacing, 1/d, time-of-flight or energy). Tools allow you to measure peak positions, intensities, and their Miller indices. You can precisely scroll the diffraction pattern, or select a plot range and zoom. Other tool buttons provide scaling functions, as well as x and y-axis offsets.
