Hi
all,
I've been
having a terrible time with spatially normalizing some T1 (MPRAGE from a Siemens
Trio) images, and every single subject has the same problem. I've research
this on the mail base, and nothing seems to help much.
First, the
whole brain images are stretched high at the top (vertex), the occipital
lobe/cerebellum are dragged down, and the y-axis is abnormally compressed.
The first and third problems resolved when I segmented the brains, and
registered gray matter to the gray apriori image, but the occipital
lobe/cerebellum is still dragged down/distorted quite severely. That
aspect seems untouched.
I seem to
have the 10/04 code fix to spm_normalise.m that addresses the Matlab 6.5
bug. Default masking doesn't seem to do anything. Quite
frustrating!
If you'd cc
reply's to me, in addition to the mail base, I'd appreciate it. Thanks to
any/all who can help.
