Description Format Details References

Description

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

Format

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.

Details

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’.
