HKL 1.98.2

HKL 1.98.2 is a collection of tools for crystallography: Denzo, XDisplayF, and Scalepack.

The HKL suite is a package of programs intended for the analysis of X-ray diffraction data collected from single crystals. It consists of three parts: XdisplayF for visualization of the diffraction pattern, Denzo for data reduction and integration, and Scalepack for merging and scaling of the intensities obtained by Denzo or other programs.

Key Benefits

  • Flexible, weighted, profile fitting algorithm for accurate measuring of the intensity of the diffraction spots 

  • Automatic indexing

  • Positional refinement  based on partially recorded reflections for high accuracy and computational stability 

  • Visualization of the data in the original form as well as the progress of data reduction

  • Scaling and merging of different data sets and global refinement of crystal parameters

Where? How?
HKL is maintained on the emu linux server.
