[Insight-users] Bspline multiRes - map outside buffer

[Sureerat Reaungamornrat]

Dear Emma,

    The error you got usually means that the overlap region between the
fixed and the moving images is too small
because the estimated transformation parameters are too far from the
optimal. Decreasing the step size of the
optimizer to constrain the length of the transformation parameter updates
usually helps. You could run B-spline
registration only at the first low-resolution level and use that
transformation to warp the moving image. Then you
could visualize the moving image with respect to the fixed image using some
visualization tools like 3D Slicer or
Paraview. This could help you understand while you got that error when you
move to the next finer level.


Best regards,

Sureerat
