RAPIDviewer: an ImageJ script for visualization and analysis of indexed electron diffraction patterns of cubic...

Area of Science:

• Materials Science
• Crystallography
• Computational Materials Science

Background:

• Indexing electron diffraction patterns is crucial for materials characterization.
• Existing tools like RAPID have limitations in visualizing indexed data.
• Accurate crystallographic analysis requires robust visualization methods.

Purpose of the Study:

• To introduce RAPIDviewer, an ImageJ macro script for enhanced electron diffraction pattern analysis.
• To address limitations of the RAPID indexing program.
• To provide advanced visualization and export features for crystallographic data.

Main Methods:

• Development of an ImageJ macro script named RAPIDviewer.
• Implementation of graphical overlays for experimental diffraction patterns.
• Inclusion of features such as spot and Kikuchi line drawings, orientation sketches, and inverse-pole-figure markers.
• Integration of VESTA file export functionality.

Main Results:

• RAPIDviewer generates configurable graphical overlays on electron diffraction patterns.
• The script includes features for orientation sketching and inverse-pole-figure generation.
• Successful demonstration of RAPIDviewer with selected-area electron diffraction patterns from austenitic steel, M23C6 precipitate, and an aluminum alloy.
• Facilitates VESTA file export for further analysis and visualization.

Conclusions:

• RAPIDviewer effectively overcomes limitations of the RAPID indexing program.
• The tool provides comprehensive visualization and data export capabilities for electron diffraction analysis.
• RAPIDviewer is a valuable asset for researchers studying crystallographic structures using electron diffraction.
