[Insight-users] DeformableRegistration4 example

[Sara Rolfe]

Hello,

I'm working through the deformable registration examples.  I'm  
attempting to use the DeformableRegistration4 example with the  
provided sample images and have run into some difficulties.  First,  
when I try to compile, I get the error:

‘class itk::SingleValuedNonLinearOptimizer’ has no member named  
‘GetStopConditionDescription’

I can get around this and compile by commenting out the line referred  
to.  However, when I run I then get another error:

THE SEARCH DIRECTION IS NOT A DESCENT DIRECTION
vnl_lbfgs: Error. Netlib routine lbfgs failed.
ExceptionObject caught !

itk::ExceptionObject (0x3b82340)

optimization


  IFLAG= -1  LINE SEARCH FAILED. SEE DOCUMENTATION OF ROUTINE MCSRCH  
ERROR RETURN OF LINE SEARCH: INFO= 0 POSSIBLE CAUSES: FUNCTION OR  
GRADIENT ARE INCORRECT OR INCORRECT TOLERANCES

Since I'm working with an example using the provided images, I assume  
this is related to my itk installation?  Please let me know if anyone  
has any leads.

Thanks!
Sara
