Hello AFNI/SUMA gurus!
I wanted to know if there was a suggested or validated way to use a combination of suma and afni (with assistance from R perhaps) to conduct a cortical thickness analysis of Freesurfer derived segmentations yielding vertex-wise cortical thickness. My specific problem is that I want to conduct a vertex-wise RM-ANOVA on cortical thicknesses and neither Freesurfer's longitudinal analysis nor surfstat offers this type of analysis.
Thank you for your advice,
Tim
