When I was reviewing the documentation for itkVersorTransform, I saw that it is recommended to use the itk:: VersorRigid3DTransformOptimizer class. However, it is the v3 version, and I have temporarily used a RegularStepGradientDescentOptimizerv4. Should I replace the entire class with the v3 version?
