RAPID-JS, a cross-platform application for instant indexing SAED patterns of cubic materials via a web-browser
Zenodo (CERN European Organization for Nuclear Research)
Abstract
ABSTRACT RAPID-JS is a browser-based implementation of the Rn-ratio method for indexing selected area electron diffraction patterns of cubic and pseudocubic materials. Implemented in Svelte/ECMAScript (JavaScript) and accelerated by precomputed lookup tables covering 136 common orientations of P, I, F, and diamond lattices, RAPID-JS allows the interactive indexing of calibrated and uncalibrated selected area electron diffraction spot patterns via a graphical user interface. The program supports the standard image formats JPG and PNG for pattern import, and returns lattice orientations and diffraction spot indices within user-defined tolerances for ratios and angles. RAPID-JS is a lightweight, cross-platform tool designed to facilitate the quick on-site analysis of selected area electron diffraction patterns in electron microscopy and crystallography research and teaching courses.The program can be downloaded as a HTML file from https://doi.org/10.5281/zenodo.18032072
