[Insight-users] itk::Transform<double, 3u, 3u>’ is not a direct base of ...

[Karthik Krishnan]

Its confusing the itk::Transform with your typedef in the line :

  typedef itk::MyTransform<double,3,3>                 Transform;

Call that

  typedef itk::MyTransform<double,3,3>                 TransformType;

instead
