If you set the p-value to .999, then you select voxels that are not activated.

Dear SPMers,
SPM5 asks me which session should be chosen when the first eigenvariate was extracted in doing PPI analysis. Our design contains 6 sessions.
I want to get the first eigenvariate from the whole 6 sessions. So which one should be chosen?
Another problem: for each subject , can I extract the first eigenvariate from the point that isn't activated.
Thanks.
Best wishes,
Junhai
