Dear Doug,
I am sorry i got confused between the thickness files lh.thickness and aparc.stats file i thought thickness measures from aparc.stats file is used to look for differences in thickness. I tried mriglm command line version and it worked so thanks, I am sorry for the confusion.
Thanks again,
venkat

How are you going to do the test? I'm not sure what the stats file has to do with the fsgd file ...

Dear All,
I am new to freesurfer, i am sorry i am confused so i am posting this message. I have two groups i want to compare cortical thickness values in all the areas reported in aparc.stats file between these two groups. So i started creating my fsgd file the problem i have is with the contrast matrix for instance i have 35 regions where thickness values are reported so i have 2*(35+1)=72 contrasts so do i need to specify each of them individually what i mean iS for instance if i am comparing lh.temporalpole (let us assume this is my first variable) so my contrast is 0 0 1 -1 0 0 0 0 ........(72 numbers) and i name this contrast as group-x-tempole.mtx then my second variable is lh.cuneus then my contrast matrix is 0 0 0 0 1 -1 0 0 0 .....(72 numbers) then i name it as group-x-cuneus.mtx. Is this the way to create or is there a simple way to this. Bottomline is i want to compare the differences in cortical thickness values between two groups in all the regions reported in aparc.stats.
Thanks
venkat
