Hello all,
I am trying to compare FDG-PET scans from 44 individual epilepsy patients
to a group of 8 normals using spm. I've used the "Compare Groups: Single
Scan Per Subject" function to compare each individual patient scan to the
group of 8 normals, with so-so results. Would it be more powerful to
compare a single patient scan to a single mean image of the normals, using
either the "Compare Groups" function or the "Single Subject: Replication
of Conditions" function? I'm unsure as to whether this would make a
difference in the statistical results, but when I attempt the latter
option it produces a blank spm report.
Any help would be greatly appreciated.
Thank you,
