Description
The ‘data_V2’ contains the second principal directions of the Orientation Distribution Function (ODF) of the fibres at each ‘data’ voxel, based on the GQI method.
Format
The file ‘data.nii.gz’ is in gzipped NIfTI format.
The R-package oro.nifti is required to read NIfTI files.
Details
The file ‘data_V2’ was produced by the function gqi.odfvmf (using the default arguments) included in gdimap.
For reasons of limited CRAN storage space, the source data set contains just 4 coronal slices as indicated in data.
