Hi Bruce,
I want to do the cortical thickness measurement and I'm not sure the workflow in FreeSurfer commands in detail, because I'm a new hand to do fMRI processing and don't know anything about brain images before.
Now for example, I have some subjects in two groups and there are 10 subjects in each group. I want to do the cortical thickness comparison between them. Do the workflow as follows?
First, I run the "recon-all -s subjid -all" for every subject(then that needs 20times). Second, do group analysis with the thickness files? Can I run the group analysis automatically?
There are something I want to clearly know: What functions should I use to get the average thickness of each group? Is there a simple function to do the work automatically? Is there a function to plot the subjects as a dot in a image and a curve to separate them?
I'm looking forward to your response. I much appreciate your help.
Thanks a lot.
