[Insight-users] landmark initialized mutual information registration

[Luis Ibanez]

Hi Raghu,

What version of ITK are you using ?

There was a bug fixed recently in this application,
related to the number of parameters used in some
Transforms.

If you want to use this application, you probably
want to use the CVS version.


   Regards,


      Luis
