Hi Xiaochu,
I'm not sure how afni stores its ROIs, but I bet Ziad (ccd) can help. I'll leave the group statistics in a label for Nick and/or Doug mris_anatomical_stats -l <label> ... will do it for an individual, so you can always run it that way, but I bet there is a better/easier way to do it.
cheers, Bruce

Hi FreeSurfer experts, I am a beginner of free surfer. Now I am working on my previous dataset with new hypothesis. In this dataset, I found a ROI (located almost in gray matter) showed significant functional difference between groups. I want to test whether the cortical thickness is changed or not in this ROI. I have done "recon-all -autorecon-all" and did some necessary check for data quality. However, I met some problems:
- The ROI dataset was from AFNI. How will I transfer into free surfer?
Which command I can use? 2. After ROI transfered, what will I do to get the averaged cortical thickness from this ROI? Are there some example or manual I can read and learn? Thanks a lot! All the best,
