Version 2.0.0 increases the number of subjects for the discrete brain segmentation to 100. The probablistic segmentation still includes only the first 50 subjects; it will be updated in the next minor release.
The Harvard-Oxford Atlas 2.0 project is developing a state-of-the-art, high-resolution full brain MR atlas consisting of 200 high definition MR data sets from the Human Connectome Project (HCP) parcellated into 392 gray and white matter PUs using structural MRI and 189 white matter fascicles using diffusion MRI. Manual parcellation will be performed based on a developed neuroanatomical ontology using a principled and well-defined parcellation methodology.
This dataset consists of 50 manual parcelations of MRI datasets from The Human Connectome Project (HCP).
Files in the dseg
directory are discrete parcelations of the subject data. Image files are in nifti format and GZIP compressed. File numbers correspond to the HCP subject number from the HCP1200 dataset.
In the lut
directory, the dseg.tsv
file describes the label values,
structure names, and suggested colors using the BIDS standard format. The
same file is stored in ctbl format for use with 3D Slicer.
The probseg
directory contains a probablistic segmentation of the atlas. See the README in that directory for more information.
Datasets have been authored using 3D Slicer using custom modules developed by the Center for Morphometric Analysis (CMA) at Massachusetts General Hospital and Brigham and Women's Hospital in Boston.
The parcellation files are derived from 3D Slicer MRB file. Because of HCP data use agreements covering the underlying datasets, we cannot publicly post the MRB files that contain that data. They are available by request.
