Dear Ce,

Your script works fine for me using some of my own images. Please note that HDW is a demanding script in terms of CPU time, especially when you have many subjects in a longitudinal study. I personally use SPM along with Parallel computing toolbox and also MATLAB distributed computing server, so the scripts can run faster. However you should be able to run HDW on a single machine with the script you have sent. You may want to upload images somewhere and I can take a look.

All the best,

Arman

Dear list and Dr.Ashburner,

Thanks for your kind response.

When running the HDW module, I ran across a problem that Matlab failed to proceed normally as it stuck at the execution of function spm_warp.

------------------------------------------------------------------------
Running job #1
------------------------------------------------------------------------
Running 'High-Dimensional Warping'
14 run_warping(job.data(i).mov{1},job.data(i).ref{1},job.warp_opts,job.bias_opts);
Generating uniform affine transformation field
Warping (iterations=8 regularisation=4)

It just stayed there for almost 3 hrs...

Has anybody run across the same problem before? I have attached my batch with the mail. The purpose is to warp the early scan to late scan within one subject. Is there anything wrong with my setup? How should I deal with it?

Many thanks and best regards,
