[Vv] clitkResampleImage

[Thomas BAUDIER]

Hi Benoit,

I have no idea, I'll talk to Simon and David after holidays.

Just one thing. Usually, we use to use clitkAffineTransform even to 
resample.
In your case, you can do clitkAffineTransform -i result.nii -l 
SUVImg.nii -o resampleCLITK.nii
and the output origin is the same than SUVImg.nii image.

Best
Thomas
