Hi Luis,
As you had indicated in a previous post, I tried to include a statement like
below in the Evaluate function of my
command observer.
 
if (optimizer->GetValue() < 30)
         optimizer->StopOptimization();
 
 
However, I got the error below. 
 
 
Building object file Registration3D.o...
/export/jfs/rsivaram/Registration/Registration3D.cxx: In member function
   `virtual void CommandIterationUpdate::Execute(const itk::Object*, const
   itk::EventObject&)':
/export/jfs/rsivaram/Registration/Registration3D.cxx:57: passing `const
   itk::VersorRigid3DTransformOptimizer' as `this' argument of `void
   itk::RegularStepGradientDescentBaseOptimizer::StopOptimization()'
discards
   qualifiers
make[1]: *** [Registration3D.o] Error 1
 
 
Is this just a casting problem, or something else?
 
 
Thanks
Radhika
