[Freesurfer] Different results for GLM analysis of parcellated regions and vertex-wise analyses

Dear FreeSurfer Mailing List, I have a sample of schizophrenia and control subjects for whom I have run a case-control analysis of cortical thickness using two separate methods (GLM vertex-wise analysis in freesurfer, repeated measures ANCOVA analysis of parcellated data in SPSS). However, for
