Dear Asaf, list,
perhaps you could do it the other way around? E.g., coregister your T1
to your functional data and leave your functional data where it is? When
you reslice your T1 during coregistration (if you really want that) the
T1 would then assume to space of your functional data. That's how we
usually do it.
It all depends a little on what you want to achieve:
when you do subsequent normalization, it really does not matter which
way you take, because images are commonly resliced after normalization
anyway (and you can set the desired reslice resolution in the defaults).
It probably takes a lot less time when you coregister the T1 to the
functional data (without reslicing) and then use that T1 to normalize to
the MNI template, using the functionals as 'other' images that simply
hitch the ride to MNI.... and it would save you one reslicing step,
leading to a bit less image deterioration.
just my 2 eurocents..
cheers,
Bas
