The HCP1065 tractography atlas is an updated version of the previous HCP842 (Yeh 2018) to the ICBM 2009a Nonlinear Asymmetric space.
The HCP1065 Yeh 2022 atlas further provides subcomponents for the cingulum, SLF, corticopontine track, corticostriatal track, and corticothalamic track (renamed as thalamic radiation).

The population-averaged templates are averaged from a group of subjects. The voxel-wise metrics are stored in NIFTI files, whereas the ready-to-track data are stored in FIB files, which can be opened in DSI Studio to perform fiber tracking.
The HCP1065 registration is based on the nonlinear ICBM152 2009a space. The template can be used with the T1W images from Montreal Neurological Institute: http://www.bic.mni.mcgill.ca/~vfonov/icbm/2009/ or histology images from the Big Brain data: https://bigbrain.loris.ca/main.php?test_name=brainvolumes
The HCP 1065 template was constructed from a total of 1065 subjects' diffusion MRI data from the Human Connectome Project (2017 Q4, 1200-subject release). There were 575 female (others male). Age ranges from 22 to 37 with a mean of 28.74, Q1=26, median=29, Q4=32. A multishell diffusion scheme was used, and the b-values were 1000, 2000, and 3000 s/mm2. The number of diffusion sampling directions was 90, 90, and 90, respectively. The in-plane resolution was 1.25 mm. The slice thickness was 1.25 mm. The diffusion data were reconstructed in the MNI space using q-space diffeomorphic reconstruction (QSDR)(Yeh et al., Neuroimage, 58(1):91-9, 2011) to obtain the spin distribution function (Yeh et al., IEEE TMI, ;29(9):1626-35, 2010). A diffusion sampling length ratio of 1.7 was used, and the output resolution was 1 mm. The analysis was conducted using DSI Studio (http://dsi-studio.labsolver.org).
