I have a question regarding snpm3 (running on SPM2). I’m pretty sure it’s a straight forward question, I’m having trouble figuring how to do a simple comparison of T1 structural scans between 2 groups.
I select design type .... "2 Groups: Two Sample T test, 1 scan/subject". I then select all my scans. The next prompt is “Enter subject Index: (A/B)” .... Can you tell me what this is in reference to?
Thanks,
Cathy
