Hi,
I might not be able to enlighten you about the exact difference between
WFU and the small volume correction in SPM. But I recently emailed the
WFU people about a similar question, namely whether using the atlas for
ROI analyses will adjust p values for the search volume, i.e. your ROI.
And apparently it does.
