Hi Chunhui
if you have the significant clusters as overlays in fsaverage you can load them in tksurfer and use the "custom fill" button to create ROIs from connected compontents that are above threshold, then go from there (e.g. mri_label2label to map them to individual subjects, etc...)

Dear freesurfer experts, I searched on the wiki but can not figure out how to solve this problem: I found some significant clusters on graymatter thickness, how can I use it as a ROI in my functional MRI study? I have both structure and function data of the same subjects, so I can either do it in stardard space or native space one by one if possible. Any help is appriciated~ Best 2014-11-20
