Dear FS experts, I want to perform asymmetry study in a group of subjects. I have created myatlas.i3 from my data(86) based on the procedure from Xhemi page and tksurfer lh inflated of both fsaverage and myatlas image is attached! it has shown that my atlas is smaller in general and larger in temporal lobe! I wonder if this is correct and I can proceed to compare left and right Hemispheres?
I'm not sure I understand what you mean by that. Your inflated brain just needs to be inflated a little more to get the folds out of it. I cannot tell whether this is sufficient or not. I found that I had to iterate many times (on the order of 30) to get stable results. This is quite burdensome, esp with 86 subjects. Have you tried using fsaverage_sym?
