Hi Somi,<br>
<br>
After comparing<br>
<br>
itkMIRegistrationFunction.txx<br>
itkSymmetricForcesDemonsRegistrationFunction.txx<br>
<br>
It seems that you are right, simply adding the<br>
method GetMetric() to itkMIRegistrationFunction.h<br>
<br>
should do the trick.<br>
<br>
<br>
Note that the internal member variable that<br>
GetMetric() should return is "m_MetricTotal"<br>
as computed in line:535 of itkMIRegistrationFunction.txx<br>
<br>
<br>
Please let us know if that works for you.<br>
<br>
The ITK registration framework is being refactored<br>
for ITKv4, and this may be something that we may<br>
want to include.<br>
<br>
<br>
Thanks<br>
<br>
<br>
Luis<br>
