Hello Mark,
Regarding my Alzheimer's dataset and the image registration , I got another strange issue.
After image registration of my functional to structural then to MNI, it seems my functional images are quite smaller than a normal brain !!!!!!! They look like a brain but a small brain comparing to my structural images.
How do I say that? I did the isotropic resampling my functional data and structural to 2 mm. Then I displayed them on FSLVIEW and saw that my functional image are smaller than structural one and doesn't cover each other !!! I think the image registration between func and struct has not been perfectly done. In the preprocessing I used 12 DOF for both registration steps . I really appreciate if you can share your thoughts with me.
Thanks,
Karen
