[ITK] Saving, reading, and applying Deformation map

[Armstrong, Hirotatsu]

Hello,

I was wondering if there was a good way to save the deformation map of a deformable registration, then re-read it to apply at a later time?  I am currently saving the map as a .vtk file, I don't know if this the most useful format.  I attached a copy of the code I am trying to use, but I am getting an error that 'itk::SmartPointer<itk::Image<itk::Vector<float,2u>, 2u> >::ObjectType' has no member GetOutput.  I am guessing that I am using the improper functions for reading in a displacement field.  Any help would be appreciated.  thanks
