[Insight-users] Translation issue in MultiResMIRegistration

[Paul Laurent]

Dear Users,

I used to use the MultiResMIRegistration from Insight Applications since 
5 years at least. It had always worked... since few months.
Now, when I use it, I get a black image...
If I change :
resampler->SetOutputOrigin( m_FixedImage->GetOrigin() );
to
resampler->SetOutputOrigin( m_MovingImage->GetOrigin() );

I get a correct registration... except that I have translation (mainly 
in Y and Z).
I have this problem with several images from several patients.

Things that have changed:
- File format: I use now Nifti instead of Analyze. Is there a trick to 
know when using Nfit Format? Initial offset contained in the nifti 
orintation matrix?
- MRI is not purely axial, there is a slight rotation. This rotation 
itself doesn't seem to be the issue since orientation are perfect in my 
Image. But maybe there is a miscalculation of pre/postTransform during 
the Preprocessor step?

Thanks for your help,
Laurent.
