I have been encountering an error with high dimensional warping, I hope someone may know a solution. I have two grey matter segment images that have been previously rigidly coregistered. The images are unsigned INT data type, 256x124x256 voxels. Nothing is unusual that I can see about the images. I am running SPM5 revision 1782, in MATLAB 7.7, on x84_64 machine running Scientific Linux (An enterprise Red Hat clone). The symptoms: All default settings were used in the HDW setup. The HDW begins and prints the following to standard output:
>> --------------------------
Running "High-Dimensional Warping"
Generating uniform affine transformation field
Warping (iterations=8 regularisation=4)

This is followed by many X's ad infinitum. I've allowed this to continue running for 15-20 minutes and it just continues like this without ever finishing the job. Recompiling the mex files in my SPM distribution using the makefile in src failed to fix the problem. Has anyone encountered this problem, any ideas?
Many thanks,
Kris
