Dear SPM experts,

 

I am making sort of digital phantom data. Using a single 3D brain nii file, duplicating it … say 40 files … now I have 40 3D brain nii files without any motion.

I want to add an artificial motion to it. My initial plan was making a dummy text file of 6 motion parameters and doing reslice of realign using the dummy file. I expected that reslice process adds an artificial motion, instead of removing motion, because my data does not have any motion. However, even though I put the  dummy text file into the same folder as image files, reslice only generate image file with ”r” prefix without any motion.

If you have any idea, could you share with me, please?

Thank you very much.
