"WebAs of the FSL 5.0.9. eddy patch, eddy will start by rigid-body registering all the b=0 and then linearly interpolate the movement parameters from those to the diffusion weighted images. If the b=0 volumes are interspersed among the diffusion images this works really well even in the presence of large subject movements. " - Dwifslpreproc
