v12.9

Changes in preprocessing pipeline (which affects your results compared to CAT12.8.2)

• The cortical surface extraction has been extensively updated with many changes that result in more reliable thickness measurements and better handling of partial volume effects.
• Initial affine registration now uses a brain mask to obtain more reliable estimates, resulting in more accurate non-linear spatial registration.
• Various smaller changes have been made for blood vessel detection and background detection for skull-stripping.
• Segment Longitudinal Data is now saving both plasticity and aging models by default.
• The previous cat_vol_sanlm from r1980 has been rescued and renamed to cat_vol_sanlm2180.m, which performs significantly better.
• The quartic mean Z-score is now used to assess sample homogeneity as it gives greater weight to outliers and makes them easier to identify in the plot.
• Several changes have been made to support Octave compatibility.

v12.8.2

Important new features

• The CAT12 manual is now converted to HTML and merged with the online help to a single HTML file with interactive Matlab links that can be called in Matlab.
• Added new thalamic nuclei atlas.
• Moved some rarely used CAT12 options to expert mode.
• Added many new options to visualize 3D (VBM) results (e.g. new glass brain).
• The tool to check Sample Homogeneity has many new options and is now based on calculation of Z-score which is much faster for larger samples.
• New Basic Models to easier define cross-sectional and longitudinal statistical designs. Some unnecessary options have been removed compared to "Basic Models" in SPM12 and some useful options have been added.
