Do you mean you want to reduce the search space of a vertex-wise analysis to a cluster or that you want to compute the mean thickness within the cluster and correlate with your behavioral score?Hi FS experts and others,I have done two group thickness difference analysis based on whole brain. Now I want to do correlation analysis between specific ROI thickness and behavior score. I searched roi in the FS website, but I cannot distinguish the volume ROI and surface ROI very clearly. So I have some questions as below:1,As I get some clusters in the two group t-test,I want to use one of these clusters to correlate thickness with behavior score. How to generate this mask and how to use this mask in the mri_glmfit and mri_glmfit-sim?
tksurfer can draw a label (as can freeview I think)2,If I want to draw ROI manually or set ROI according previous studies, how to create this ROI mask.
Any detailed information will be highly appreaciated.Thanks.All the best.Rujing Zha
