<DIV>Hi, Julien,</DIV>
<DIV> </DIV>
<DIV>Thanks a lot for your reply. I wonder if ITK has a function to get the rotation angle for each iteration for every registration method, such like demons, multi-resolutional and so so, not only for itkEuler3DTransform. Is GetCurrentPosition able to do so? </DIV>

<DIV>Thanks</DIV>
