Dear SPMers,
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:
/Users/neurolabII/Desktop/newly_processed_scans/80
--------------------------
Running "High-Dimensional Warping"
Generating uniform affine transformation field
Warping (iterations=8 regularisation=4)
9.9772625
nan
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
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.
