Dear all,
Having realigned and normalised some images I find that SPM
now estimates their smoothness at (2.4 2.4 3.2 voxels).
(http://www.jiscmail.ac.uk/cgi-bin/wa.exe?A2=ind0003&L=spm&P=R24140)
Assuming that I do not particularly wish to smooth this data,
may I proceed directly to GFT inference?
Also, in other situations, might I simply resample data at much
higher resolution, smooth it by two voxels and then feed it back
into SPM inorder to fulfil GFT assumptions whilst effectively
maintaining near original resolution?
Surely life is never this simple?
Regards,
Afraim
