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

Dear Rahul The SI is primary somatosensory cortex (or postcentral gyrus) and MI is primary motor cortex (or precentral gyrus). I want to compare the thickness and volume of these two areas from left side to right side. Thank you,

Hi Xin,
What exactly do SI and MI cortices refer to?

Hello, group I need to compare thickness of left v.s. the right SI and MI cortices. I saw some matlab tools for comparsion of left and right hippocampus in Lundervold.pdf. 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? Thank you in advance.
