Dear SPMers ,
I have to do a group analysis to do, and i would like to make an random effects with the one paired t-test model. With my image, i can do a group analysis with fixed effetcs , that just means that all my images have the same dimension.
But when i create my t-contrast (based on the same model) and when i launch the one paired t-test model with all the correspondant con???.img files, matlab answers me that my images have not the same dimension? I dont understand where it can come from.
I really need help plz =)
I work with SPM2 and Matlab 6.5
