[Freesurfer] Cortical thickness values extraction issue

2019-02-15 Thread Giuliana Klencklen
to solve this problem, what combination of arguments should I use? And if this is not, do you have any idea how I can solve this problem? Many thanks in advance. Regards, Giuliana -- Giuliana Klencklen, Ph.D. Helen Wills Neuroscience Institute University of California, Berkeley 118 Barker Hall

the overlay does not show at all the significant clusters summarized in the something.sig.cluster.summary. I run the mri_glmfit-sim command again but the problem persists. Does anyone have a clue about what is going wrong? Many thanks, Giuliana Klencklen -- Giuliana Klencklen, Ph.D. Helen
