Hello, Rahul
Two more questions. 1. How can I get the volumes of subcortical structures, like in the presentation of freesurfer & matlab? I did not find the matlab script to do so.
2. where are the thickness of every voxel saved? Can I access to it and copy data out?
Many thanks to you and Doug

Hi Xin,

Within the *h.aparc.annot files for each subject, there should be
individual label files for *h.precentral.label and *h.postcentral.label.
If you take a look at your *h.aparc.stats, there should be a value for the
thickness and volume. You can, of course, take this *h.aparc.stats file
and upload it into matlab, spss or any other stats package and do
statistics on these values.

Best,

rahul

I could not find similar tools in the matlab folder of Freesurfer stable release 3.0.5 that I just installed. Could anybody kindly tell me the tools I could use for my study?
