Sinc interpolation is generally recommended for interpolation
when doing movement correction. If you reslice the images at
the realignmnt step, then I don't think you gain much by
using sinc interpolation at the normalisation stage. However,
if you just estimate the movement parameters at the realignment
stage, then these movements are incorporated into the spatial
transformations at the normalisation stage, so it is probably
better to use sinc interpolation.
