Dear SPM users
I have done VBM between two groups with SPM2.
Because the groups are different in sizes
I have used non-sphericity correction (replications about
repl --> subjects). Although I have built two identical
models the design matrices look different in the third column
(see attachement).
Is this only a failure in the graphics of SPM2 or is there something
wrong? Why is the third column different in the design matrix between
the model for GM and the one for WM?
Thanks a lot for helping
Best regards
Juergen
