Electron diffraction technique is widely used for the phase identification and crystal structure determination of Earth and planetary materials. In the present study, the authors developed a GUI-based software that simulates electron diffraction patterns using dynamical theory. In the presentation, the authors will report examples of reproducibility of simulated diffraction patterns (SAED and CBED) for several minerals, and future prospects of this approach.
