Dear SPM authors
Today I ran a conjunction analysis ... and something seems to bug?!
The design matrix is a 6 conditions within subjects ANOVA with 12
subjects. I performed several contrasts like 1>4, 2>5 and 3>6. Next, I
performed the conjunction (1>4)+(2>5) and SPM created a new contrast
that corresponds to this conjunction. But, when I look at the result of
this new contrast, it's different than the one obtained by (1>3)+(2>4)
??? I tested with other conjunctions .. same results! any suggestions?
what is the good result ? does anyone have encountered this problem?
Thank you
Cyril
