Dear Freesurfer Experts,
I did a longitudinal 2 stage model and now I would like to extract the thickness and area values from significant clusters that survived the Monte Carlo correction.
As I understood from the various e-mails in the archives expressing the same request there is a file "something.y.ocn.dat" where those thickness values are supposedly stored for each cluster and each subject. However, this file included "the average value of each subject in each cluster" (as it states in the group comparison tutorial), meaning the -log10(pvalue).
I would like to show that the significant difference between two groups is driven by a certain group and to do that I want to display the thickness and area values of each cluster in bar graphs.
What could I do to receive these values?
Cheers, Clara
