I'm afraid I can't figure out the cause of this problem. Did you reslice
can think of that may help.
I'm beginning to explore the technique of deformation-based morphometry. I
have longitudinal T1 images from the same subject. I've performed
preprocessing on the images including resetting the origin, skullstripping,
and registering (aligning) the later scan to the earlier scan. When I try
to run high dimensional warping on the images in SPM5, however, I get the
following output:
Initialising SPM.........done
SPM present working directory:

Running "High-Dimensional Warping"

Warping (iterations=8 regularisation=4)

The program keeps printing "Xs" and I have to force quit Matlab. I am able
to use the SPM2 deformations utility on these images, however, and obtain a
jacobian determinant image (jy_*). Any idea why I am having this trouble
with SPM5, but not SPM2? Is there any advantage of SPM5 over SPM2 for high
dimensional warping? Thanks in advance for any insights you may be able
to offer.
