[Insight-users] deformation field

[Vidya Rajagopalan]

Hello Ming,

VTK sometimes has problems with deformation fields generated in ITK
(*.vtk format). VTK sometimes cannot read the header output by ITK. If
you are saving the deformation fields as *.vtk files, trying saving them
as *.mha. This has worked for me in the past.
GoodLuck,
