I'm currently limited to SPM2 (Matlab 6.5.0 ver 13.0.1) and I'm trying to
finesse the spatial normalization parameters to correct the following
issue. I'm normalizing to the MNI152 template and while the x- and y-
outcomes look just fine in the central and lower slices, the resulting
warped image is "stretched" in the z-direction (top of brain only).
The best results have come from:
(don't weight sources)
(extra heavy regularization)
(16 nonlinear iterations)
I hope someone's encountered this before and can provide a solution (or at
least point me in the right direction). I don't particularly want to skull-
strip if there's a simpler fix.
