(2) Debug Results:
line 115 of function spm_preproc8:  param=[2  sk.*vx  ff*obj.reg*[1 1e-4 0]];
in which, sk=[3,3,3], vx=[1.0000,1.0001,1.0000], ff=4.6292, obj.reg=[0,0.001,0.5,0.05,0.2], i.e,, dimentsion of obj.reg don't match with [1 1e-4 0].
The automasks it generated wasn't right, either. Pls refer to the attachment pic file.
(3) Configuration
The configuration works well with demodata provided by this website.  I only changed the parameters for slice timing using user-defined .tsv file containing accommodated slice order infomation.
Thanks in advance for any possible solutions.

I think there is some problem with this specific data.

Dear Dr. Yan,

    I've been trapped in this error for days.  My Fun images are 94 x94x75x240, and T1 images are 248x256x176 in size.

    Any idea what the problem might be?  Great thx.

All the best,

Try another subject or another dataset to see if the software works. Then debug from there.
