Our research group is going to do VBM by using the newest version of SPM. The original DICOM mri dataset is 3D. Is it necessary to have the dataset in the same form (e.g. 3D) even after conversion to NIfTI or is necessary
to transform the data to 2D (e.g. axial slices) before starting the VBM analysis. I suppose the former (e.g. to maintain it 3D) is correct?
