[Insight-users] Question: Deformation fields

[Karthik Krishnan]

Could you describe in detail how you are visualizing the deformation 
field in Paraview. Please read the section on the SoftwareGuide titled 
"Visualizing 2D Deformation fields" in Paraview.

[ I assume you are loading the file and glyphing it right away. That 
would glyph the magnitudes of the field vectors, which being scalars 
would point right/left. You need to use the calculator to convert this 
to a 2 D vector field and glyph that. More in the guide..... ]
