This repository hosts code designed to convert uxd-format files from an XRD machine into CSV files. These files are subsequently used for graphical representation and analysis of properties such as: FWHM, theta and crystallite size using the Debye-Scherrer and Williamson-Hall formulas. All of this is carried out using Python.
