[Vv] Problem with clitkAffineTransform

[Benoît Presles]

Hello Thomas,

Thanks for the hint. Indeed, when I use this option, ROI_PET.nii is not 
empty anymore.
Can you tell me more about this option ?

First, I thought that this option was only necessary when used in 
combination with --size or --spacing, etc. not with the -l option.

Second, I have noticed that the only difference between 
clitkAffineTransform -i ROI_CT.nii -o ROI_PET.nii -l PET.nii --interp=0 
-v --adaptive and clitkAffineTransform -i ROI_CT.nii -o ROI_PET.nii -l 
PET.nii --interp=0 -v is the origin of the output image.
Without the --adaptive, the ROI_PET image has the same origin as the PET 
image but with the --adaptive option, the origin of the ROI_PET image is 
slightly different.


Thanks for your help,
Best regards,
Ben
