Dear Megan,
it will be better to feed in the original data. Partly because you
will avoid an unnecessary resampling and partly because the first
alignment (to the anatomical scan) will have created chunks of zeros
in the realigned images that might otherwise confuse the registration.
Good luck Jesper
