Gwaihir: Jupyter Notebook graphical user interface for Bragg coherent diffraction imaging

J Appl Crystallogr. 2022 Jul 15;55(Pt 4):1045-1054. doi: 10.1107/S1600576722005854. eCollection 2022 Aug 1.

Abstract

Bragg coherent X-ray diffraction is a nondestructive method for probing material structure in three dimensions at the nanoscale, with unprecedented resolution in displacement and strain fields. This work presents Gwaihir, a user-friendly and open-source tool to process and analyze Bragg coherent X-ray diffraction data. It integrates the functionalities of the existing packages bcdi and PyNX in the same toolbox, creating a natural workflow and promoting data reproducibility. Its graphical interface, based on Jupyter Notebook widgets, combines an interactive approach for data analysis with a powerful environment designed to link large-scale facilities and scientists.

Keywords: Jupyter Notebook; X-ray diffraction; coherence; graphical user interfaces; phase retrieval.
