Profex 4.2 released

August 05, 2020. Profex, our software for Rietveld refinement of powder X-ray diffraction data (XRD), continues to gain popularity and is now established worldwide in the material and earth sciences communities. With the new version 4.2, it has received some long-awaited features that make it easier to use for new and experienced users. As always, Profex remains available as open-source software and is free for academic and commercial use. Visit the What’s new page for an overview of the new features, and download the latest version for Windows, Mac OS or Linux from the Download page.

Feature highlights in version 4.2

Import of CIF structure files has further been improved. Most CIF files require no user input anymore. Wyckoff symbols are determined automatically.

Creating instrument configurations has always been a major obstacle for new users. A brand new graphical instrument editor is easier and more attractive to use. It guides users through the process of creating configuration files for their own devices.

The search-match module for phase identification was introduced with Profex 4.0. With version 4.2, it supports chemical restrictions, which gives more control over the search process and improves the match rate and processing speed.

What is Profex?

Profex is a graphical user interface for Rietveld refinement of powder X-ray diffraction data with the program BGMN. It provides a large number of convenience features and facilitates the use of the BGMN Rietveld backend in many ways.

  • Main window

Key features

  • Support for a variety of raw data formats, including all major instrument manufacturers (Bruker / Siemens, PANalytical / Philips, Rigaku, Seifert / GE, and generic text formats)
  • Export of diffraction patterns to various text formats (ASCII, Gnuplot scripts, Fityk scripts), pixel graphics (PNG), and vector graphics (SVG)
  • Batch conversion of raw data scans
  • Automatic control file creation and output file name management
  • Conversion of CIF and ICDD PDF-4+ XML structure files to BGMN structure files
  • Export of refined crystal structures to CIF and Castep CELL format
  • Internal database for crystal structure files, instrument configuration files, and predefined refinement presets
  • Computation of chemical composition from refined crystal structures
  • Batch refinement
  • Export of refinement results to spreadsheet files (CSV format)
  • Context help for BGMN variables
  • Syntax highlighting
  • Enhanced text editors for structure and control file management and editing
  • Generic support for FullProf.2k as an alternative Rietveld backend to BGMN
  • And many more…

Profex runs on Windows, Linux, and Mac OS X operating systems and is available as free software licensed under the GNU General Public License (GPL) version 2 or any later version.
