Dear SPM experts,
I have now analyzed the data of PET activation experiment.
Using 'Full factorial', I created a 2 x 2 ANOVA design matrix
in order to calcluate two main effects and an interaction.
Whereas this process can automatically generate the contrasts
necessary to test for all main effects and interactions in "2nd-level"
analysis for fMRI data, my design matrix for PET data cannot
automatically generate such contrasts.
I would like to know this reason and how to resolve this problem.
Any help would be greatly appreciated.
