This dataset contains segmentations of 72 white matter tracts obtained from 105 subjects included in the Human Connectome Project (HCP) Young Adult dataset (https://www.humanconnectome.org/study/hcp-young-adult). The folder names in the source archive correspond to the HCP subject IDs. This dataset contains only tracts; the original DWI data must be downloaded separately from the HCP website (free registration required).
Details
The included bundles are stored as objects of class fiber::bundle.
A fiber::bundle object is an S7 class which has two slots: @streamlines
and @bundle_data, where:
@streamlinesis a list of fiber::streamline objects, which, in turn, are S7 classes with slots@points,@point_dataand@streamline_data.@bundle_datais a list of metadata about the bundle, such as its name, where it was extracted from, etc.
More details about the format of the data can be found in the documentation of the fiber package.
TractSeg
Per-subject white matter bundle segmentations generated with TractSeg from
105 HCP subjects. Each bundle is hosted in a dedicated GitHub release
(tractseg-<bundle_name>). Assets are named
TractSeg_<subject_id>_<bundle_name>.rds.

HCP Data Terms
The source tractograms are derived from the Human Connectome Project Young Adult dataset. Users must comply with the applicable HCP data-use terms and acknowledgment requirements.
Modifications
The original .trk streamline files from the Zenodo archive have been
converted to R fiber::bundle objects and serialised as .rds files using
the mascot package pipeline. No spatial or statistical modifications were
made to the streamline data. Bundles are split one per GitHub release tag.
