= Goals =
There are three objectives:
* '''Inter'''-Subject, '''Diffusion-to-Diffusion''', '''affine''' registration
* '''Inter'''-Subject, '''Diffusion-to-Diffusion''', '''non linear''' registration.
* '''Intra'''-Subject, Diffusion-to-Structural '''affine''' registration.

= Data =
We will provide the following data in NRRD format for 4 cases:
* 1.5T Coronal series of contiguous spoiled gradient (SPGR) images (voxel dimensions, 0.9375x0.9375x1.5mm). (caseX_SPGR)
* 1.5T Axial series of contiguous double-echo images (Proton Density and T2 Weighted, (voxel dimensions, 0.9375x0.9375x3mm). (caseX_T2; caseX_PD)
* 1.5T Line Scan Diffusion Imaging (LSDI) scan. 6 directions, (voxel dimensions, 0.859x0.859x5mm).(caseX_DWI)
* 3T 3D FSPGR Axial, (voxel dimensions, 0.5x0.5x1mm). (caseX_SPGR_3T) 
* 3T T2 Axial 2mm, (voxel dimensions, 0.859x0.859x2mm). (caseX_T2)
* 3T Echo Planar Imaging (EPI) Diffusion scan, (voxel dimensions, 0.9375x0.9375x1.7mm). (caseX_DWI_3T)
