The article introduces JANA2020, the latest version of a powerful crystallographic computing system used for solving, refining, and analyzing crystal structures. JANA2020 builds on its predecessor, JANA2006, by offering a modernized graphical interface, improved tools for handling complex structures, and enhanced support for twinned and magnetic structures. The program is designed to be intuitive for both simple and advanced crystallographic tasks, making it accessible to a broad scientific community.
JANA2020 can process data from X-ray, neutron, and electron diffraction experiments, and it supports both standard and modulated structures, including those with magnetic ordering or twinning. The software integrates advanced visualization tools, such as JANADRAW, which allows users to interactively view and edit crystal structures and analyze electron density maps. This is particularly useful for understanding the arrangement of atoms and the effects of structural modulations. The program also features robust symmetry analysis, automated refinement procedures, and the ability to combine data from multiple sources for a single structure model.
A key improvement in JANA2020 is its user interface, which streamlines the workflow and connects graphical structure plots directly with editing and analysis tools. This makes it easier for users to manipulate structural parameters and immediately see the effects of their changes. The software also supports the export of results in standard formats for publication and further analysis.
