Dear all,
During pre-processing the fMRI data, I found that the segmentation on the T1 which was coregistered with the mean fMRI image is bad. I check that the origin of the mean fMRI image is very off from the AC, which is near the bottom of brainstem. I also tried segmenting the T1 before any coregistration (while its origin is still near AC) and found that the segmentation is perfect. This means the problem is the origin of the fMRI image. In this case, should I reorient all the fMRI images to change their origins to AC? If yes, will this step create any problem to the fMRI data?
Thanks for your reply!
Best wishes,
Meikei
