Dear SPM expert,
I have a simple question about conjunction analysis.
I can find the way to perform conjunction analysis in 2nd level group
comparison in e-mail list. But I don't know how to perform conjunction
analysis in first level (one group).
I wonder wheter my thought like below is correct or not.
If I have 2 contrast (con1, con2) in each subject and I could see the
result of conjunction analysis with shift key but could not get con*.img
file at each subject level. So I think, in second-level analysis, I should
select 'one-way anova' for first level (one group) unlike 'one-way anova
(not with constant or within subjects anova) for 2nd level analysis.
But I'm not sure whether I should select 'within subjects anova' or 'with
constant' option or other way for first level (one group).
I'd be very happy if someone could tell me how I should do.
Thank you for advance,
