Hi, I tried to test FS cortical thickness analysis by using a batch of 10 subjects whose grey matter I manually deleted in the temporal lobes (a significant part at least). When I compared it to the original 10 images, little or none changes were significant! I checked the segmentation and I noticed that the grey/white boundary in the original subjects was too conservative, hence no changes were detected (at least I believe it is the only explanantion).
Is it possible to change the segmentation parameters to make it more "agressive" or am I overlooking something? Thank you!
