Thanks, Steve.
sorry I didn't dig the FAQ before sending out the question.
I did search the mailing list archive, though, and I found a thread where an approach of doing the cross-subject analysis with all first level (session) results was suggested in 2005 (with multiple EVs for multiple subjects). I guess this approach will give the same cross-subject result if only the copes are passed to the higher level analysis?
Cheers,
George

Hi - you should be able to feed that single subject's first-level results into the 3rd-level analysis - see the FAQ entry on this.
Cheers, Steve.

Hi,
I have a study that each of the subjects had 2 sessions, except one subject who had only one session.
When it comes to find the group mean, how do I set the model up?
Normally if all subjects had at least 2 sessions, I can do a cross-session first (as 2nd level) and then do a 3rd level to get the group mean.
But for the subject that had only one session, I cannot do a cross-session, then what do I feed to the 3rd level design?
Thanks,
George
