Dear SPMers and Dr. Ashburner:
I have a data set, consisting of:
(1.) 10 schizophrenic pairs, first scanned on antipsychotic medications,
then scanned four weeks later off antipsychotic medications. These are the
"subject group".
(2.) 8 schizophrenic pairs, first scanned on antipsychotic medications, then
scanned four weeks later on the same antipsychotic medications. This is my
"control group".
I would like to use the optimized VBM morphometry protocol (of Goode, et
al,) to detect significant differences in volume change between the
"subjects group" (ON--> OFF group) and the "control" group (ON--->ON group).
Where should I start with the preprocessing and normalization of these
images?
Thank you,
Rob McClure
