version 20-July-2022 (v1.2.20220720)

• Linux fonts with bitmap zoom > 1
• MRS data types
• Updated dcm2niix
• The MRIcroGL_linux1804 archive is for older (e.g. Ubuntu 18.04) Linux distributions. Users of modern distributions should us the MRIcroGL_linux archive.

To use the QT5 version, Linux users may need to install libqt5pas1 (e.g. sudo apt install libqt5pas1). If this is not included with your distribution, you can either use the GTK version or install the libqt5pas1 library manually.

version 7-October-2021 (v1.2.20211007)

Draft for Debian code

version 6-October-2021 (v1.2.20211006)

• Interactive render crosshairs for the Multi-Planar A+C+S+R menu item in the Display item shows 2D slices and a volume rendering. Clicking on any of the four images changes the cross-hair position across all views. The method is described here.
• The Option button includes Find Edges command that provides a Difference of Gaussians. Also available in scripts via dog() function.
• Measuring tool (option-drag across slices) shows sample along line graph.
• Intensity histogram function in Graph menu.
• Updated dcm2niix

version 1-August-2021 (v1.2.20210801)

Minor release

• By default builds to PythonBridge instead of Python-for-Lazarus. This allows static linking for macOS and Linux.
