[Insight-users] Deformable Registration Example Difficulties

[Dr. Tim Allman]

I have been having some problems with BSpline based registration. I get 
the same results with "out of the box" builds on both my iMac and Linux 
Mint.

This is the output from the DeformableRegistration4 example. The code is 
not modified.
