Hi all,

   I am using the \examples\MultiResImageRegistration2.cxx for my image registration. I gave 2 MRI(256X256) images as inputs. Fixedimage is a normal image but Moving image is a rotated image rotated in z with 2 degrees. Now when i run the application, with out changing other code, i get a exception from itk. I have pasted the error message below of this mail. Please help me in solving the problem. The same code is working when i give a translated image(10,10) as a Moving image. It is registering both the images perfectly. But when coming to rotation it is giving this error. Please help me in this regard. Also send some info on JointPDF due to which this error is generated.

   Thanks in advance.

-Regards,
   Valli.
