Version 3 of the MIITRA atlas is now available and contains labels!

Labels from a total of 30 labeling schemes / atlases are now available in MIITRA space (both in 1mm and 0.5mm resolution) e.g. AAL, Brodmann, Desikan-Killiany, von Economo, HCP, Julich, Shen, Yeo labels just to name a few. To generate them, labels from 30 different labeling schemes / atlases were applied to all 400 older adult participants of the MIITRA atlas in native space, then all labels were transformed to MIITRA space, and majority voting was used to generate the final labels in MIITRA space. The sets of labels made available in this version are based on structural, cytoarchitectonic, and functional connectivity information and substantially enhance the functionality of the MIITRA atlas.

In addition, the new version of the atlas includes gray matter masks and a new manual.

Version 2 of the MIITRA atlas of the older adult brain is now available. The current version includes high-quality T1-weighted & DTI templates of the older adult brain, as well as tissue probability maps and other resources at both 0.5mm and 1mm isotropic resolution. The MIITRA templates were constructed using advanced multimodal template construction techniques on data from a large, diverse, community cohort of 400 non-demented older adults and a) are well-matched in space, b) exhibit high image sharpness, c) are free of artifacts, d) provide high inter-subject and inter-modality spatial matching of older adult data, and e) are highly representative of the older adult brain.
