[Vv] Problem with clitkAffineTransform

[Benoît Presles]

Dear vv users,

I am trying to resample a ROI image (ROI_CT.nii) like the corresponding 
PET image (PET.nii) doing the following command line :
clitkAffineTransform -i ROI_CT.nii -o ROI_PET.nii -l PET.nii --interp=0 -v

The resulting image (ROI_PET.nii) is black. Here is the link to download 
my data : https://cloud.u-bourgogne.fr/index.php/s/MFbfmeaEBEQRgnz/download

Thanks for your help,
Best regards,
Ben
