HCP1065 tractography atlas (April 2020)

HCP1065 atlas is an updated atlas from HCP842 atlas. The new atlas is baes on "ICBM 2009a Nonlinear Asymmetric" (https://www.bic.mni.mcgill.ca/ServicesAtlases/ICBM152NLin2009) space, whereas HCP842 is based on FSL's FA map ( 58 FA images averaged to old MNI152). The new atlas further provides subcomponents for cingulum, SLF, corticopontine track, corticostriatal track, corticothalamic track (renamed as thalamic radiation). Since the atlas is transformed or derived from HCP842, please cite the original HCP842 atlas paper (Yeh, 2018), and mentioned an updated version is used to get tracks in the ICBM152 nonlinear space.

        (DSI Studio can open *.tt.gz and *trk.gz directly without decompressing them)

To view these tract files, please download the HCP-1065 template fib file and open it in DSI Studio at [Step T3 Fiber Tracking]. The *.tt.gz files can be loaded using [Tracts][Open Tracts]. The ICBM152 images can be loaded using [Edit][Insert T1W/T2W].

HCP842 tractography files (2018)

HCP842 tractography atlas uses FSL's FA map as its reference space (https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/Atlases), which averages from 58 FA images in the MNI152 coordinate. 

     A total of 80 nifti files are available in the download link. Each file records the voxel-based mask converted from the trajectories of fiber bundle. The original tracks has a much high resolution, and the conversion to a voxel mask loses a substantial amount of spatial information. 
     A total of 80 TRK files are available in the download link. To view these TRK file, please download the HCP-842 template here: https://pitt.box.com/v/HCP842T. open it in DSI Studio at [Step T3 Fiber Tracking]. The TRK files can be loaded using [Tracts][Open Tracts]
     The pictures show views of the fiber pathways from 6 different directions in a higher resolution. The images were created using DSI Studio.
     Connectograms of each fiber pathway generated using an AAL-based brain parcellation.
