NTU-DSI-122.nii.gz
A DSI template constructed in the ICBM-152 space from 122 healthy adult subjects. The dimension is (x, y, z, q) = (181, 217, 181, 102), where x, y and z refer to the image space and q indicates the q-space. The b-values and diffusion gradient vectors of the q-space points are stored in NTU-DSI-122.bval.txt and NTU-DSI-122.bvec.txt, respectively.
NTU-DSI-122.bval.txt
The b-values (sec/mm^2) of the q-space points stored in NTU-DSI-122.nii.gz.
NTU-DSI-122.bvec.txt
The diffusion gradient unit vectors of the q-space points stored in NTU-DSI-122.nii.gz. The first, second and third rows represent the qx, qy and qz coordinates, respectively. Note that the orientation definition follows the MNI space convension, i.e., +xyz = RAS.
