Kent,
Please initialize this variable to an identity transform so that if it is not explicitly specified that it will have the correct value.

Subject: BRAINSABC Bug
If you run BRAINSABC from the command line without the —atlasToSubjectInitialTransform option it will seg fault on line 433 of AtlasRegistrationMethod.hxx because the variable m_AtlasToSubjectInitialTransform was not being initialized in this case. I just tried a test where I set this variable to NULL in the class initializer and the segmentation fault here was eliminated. However it is still seg faulting in the ITKv4 Registration.
