PDFgetX3 is a simple yet powerful program for converting X-ray powder diffraction data to atomic Pair Distribution Functions (PDFs). PDFgetX3 can be used in a batch mode to convert a series of data files without user intervention. PDFgetX3 can be also run in an interactive mode that allows to control process parameters and plot the PDFs and any intermediate results. Users can interactively tune the PDF processing parameters, visualize their effect on the results and adjust them to their optimum values. The PDFgetX3 software comes with a Python library of PDF processing functions, which can be easily used in custom Python scripts.
