[Insight-users] RuntimeError about MutualInformationImageToImageMetric:FixedImageRegion is empty

[Luis Ibanez]

Hi Carrie,

You probably forgot to invoke the method

        SetFixedImageRegion()

from the ImageRegistrationMethod before
invoking StartRegistration().

Please look at the SoftwareGuide for details
on how to use this method

  http://www.itk.org/ItkSoftwareGuide.pdf

In particular look at Section 8.2, pdf-page 242.
(the method is shown in page 244).



  Regards,


     Luis
