Greetings,
I did a second level ANOVA in SPM, and noted the peak (most significant)
voxel for the interaction. As a sanity check, I went back and wrote down
the betas for each subject for this voxel and did an offline two-way
ANOVA in Matlab. I didn't get anything close to significant. Could
someone please explain why?
Thanks,
karli
