Actually, I am testing "ImageRegistration8.cxx" in the example. But I came across with this error:</div><div><br></div><div>parameters: [0, 0, 0, 9.60149, 1.8091, 7.27435]</div><div><br></div><div>ExceptionObject caught !</div><div><br></div><div>Description: itk::ERROR: MeanSquaresImageToImageMetric(0x2105f30): All the points mapped to outside of the moving image</div><div><br></div><div><br></div><div>I searched the internet, and knew that this might be something related to the initializer, but I still cannot fix it. Any suggestions?</div><div> Thanks in advance. <br></div></div></body></html>
