data.bvec: 3D b-table Vectors for Data Acquisition

Description Format Details References


3D grid file containing the sampling points used in diffusion data acquisition for file ‘data.nii.gz’.


data.bvec’ is in ASCII format, specified as a sequence of values, as produced by the 'dcm2nii' tool, and compatible with the formats used in the 'DSI_Studio' and 'Dipy' toolboxes.


The file ‘data.bvec’ has 203 points uniformly distributed on a 3D (DSI) grid limited to the volume of the unit sphere. The data set ‘data.nii.gz’ is NIfTI-converted from the DICOM data set provided by the Advanced Biomedical MRI Lab, National Taiwan University Hospital, under the designation ‘DSI 203-point 3mm’.
