 ====Case 2 (Archana)====
-In this short tutorial, we will show how the Affine Registration module can be used to register two images from different subjects.  The data is from the [http://www.oasis-brains.org/ Oasis Brains project] and the [http://www.loni.ucla.edu/Atlases/Atlas_Detail.jsp?atlas_id=6 ICBM.  We will be registering the volumes icbm452_atlas_air12_sinc.hdr and OAS1_0001_MR1_mpr-1_anon.hdr.  Be sure to load the volumes with the "Centered" option checked.  Rotation is performed around the center, and a centered volume usually produces a more robust result.
+In this example, the Affine Registration module is used to register the mean fMRI image to the baseline DWI image of the same subject. The fMRI data is motion corrected and slice timing. The first four volumes are discarded for stability reasons. The data is then averaged over time to compute the mean fMRI image. The diffusion weighted images are eddy-current corrected and smoothed. The tensors and baseline image are extracted using the Diffusion Tensor Estimation module. These images are loaded into Slicer, and the Register-Affine Registration module is selected:
