I will Doug handle this one. And please email the list in your replies.

Many thanks, Rahul. I found readings in /stats/*h.aparc.stats. I am a freesurfer beginner. I have another question. I want to compare the cortical thickness between two small groups (2X2). I can not work through the steps in the tutorial on my data. The mri_glmfit commend always returns with "bad design, ill-constructed," and stops. Do you have any detail instructions of two group comparison? Thank you again,
Xin

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,

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.

Hello, group I have problems to save the display in TKsurfer. I tried 'Save RGB as', but I could not open the file with photoshop in windows, and it was total black when I opened it with adobe illustrator in windows or GIMP in Linux. Please tell me how to save the images so that I can open them with photoshop. Thank you in advance,

The RGB format is an old Irix format, I think. The UNIX/Linux program 'convert' should be able to convert it to a jpeg for you.
