HCP1065 Population-Averaged Tractography Atlas

Source: R/HCP1065.R
HCP1065.Rd

The HCP1065 population-averaged tractography atlas is an updated atlas from the HCP842 version. The new atlas relies on 1,065 subjects and is based on ICBM 2009a Nonlinear Asymmetric space, whereas HCP842 relied on 842 subjects and was based on FSL’s FA map (58 FA images averaged to old MNI152). The new atlas further provides subcomponents for cingulum, superior longitudinal fasciculus, corticopontine tract, corticostriatal tract, and corticothalamic tract (renamed as thalamic radiation).

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:

  • @streamlines is a list of fiber::streamline objects, which, in turn, are S7 classes with slots @points, @point_data and @streamline_data.

  • @bundle_data is 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.

HCP1065

A population-averaged tractography atlas based on 1,065 HCP subjects. See HCP1065 for full details, source, and references.

HCP Data Terms

The atlas is 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 DSI Studio / Fiber Data Hub release have been converted to R fiber::bundle objects and serialised as .rds files. No spatial or statistical modifications were made to the streamline data. All 87 bundles are hosted together in the single hcp1065 GitHub release of this repository.
