DATASET DESCRIPTION

This atlas is composed of a population average ex-vivo MRI T2WI contrast mapped with the BMA 2017 Ex Vivo (published by Woodward et al. The Brain/MINDS 3D digital marmoset brain atlas).
The population average MRI was constructed based on scans of 25 individual brains. The 25 brains were aligned with one another by iteratively applying linear and non-linear registration and averaging the transformation files until convergence. Data of individual brains were then resampled with an isotropic spatial resolution of 100×100×100µm3 and averaged across brain. The registration procedure gave a brain shape with a high signal-to-noise ratio compared to an individual MRI scan. The average MRI was then AC-PC aligned within an RAS (Right-Anterior-Superior) coordinate system.
Cortical flat map and mid-thickness surfaces for the left and right hemispheres are now provided in the common GIFTI format (*. gii) for surface data. These are compatible with Connectome Workbench (version 1.5.0 and higher) and a Scene file is also provided for easy viewing of the data.
