Data for "TrueEBSD: correcting spatial distortions in electron backscatter diffraction maps" published in Ultramicroscopy. Journal DOI: https://doi.org/10.1016/j.ultramic.2020.113130; Preprint DOI: https://arxiv.org/abs/1909.00347. The zipped folder contains: Readme (text file) 'Ti-64' data subfolder: data for one of the maps in the Ti-64 map stitching example 'ZrH' data subfolder: data for the hydride-containing Zircaloy-4 example 'CP-Zr' data subfolder: data for the in-situ deformed Zr example 'MATLAB scripts' subfolder: TrueEBSD source code. Each data subfolder contains: Input image files EBSD orientation files in Bruker CTF format 'Outputs' subfolder containing output figures as image files. The 'MATLAB scripts' subfolder contains TrueEBSD source code: The primary user interface is 'input_deck.m'. Most user settings can be changed here. The input deck entries here have been pre-filled for the Ti-64 dataset. To use TrueEBSD, run 'input_deck.m' in MATLAB. The method is outlined in 'main.m', which calls functions in 'MATLAB scripts\code\'.
