[Insight-users] FEMRegistration warped image orientation

[Perhavc]

Hey!

The second problem i experienced as well. The problem is that in new releases of itk, the orientation of the Analyze format is not set by default to RIP(coronal). If orientations are ignored in the code, the exception is thrown. Therefore you need to set the direction of the images via SetDirection() to set them to a supported analyze orientation in order to write them as an analyze file. Bellow is a simple code snippet that assigns the orientation:

// SET THE ORIENTATION FOR WRITING ANALYZE IMAGES
	typedef itk::OrientImageFilter<ImageType,ImageType> OrientImageFilterType;
	OrientImageFilterType::Pointer orienter =OrientImageFilterType::New();
	orienter->SetInput(reader->GetOutput());
	orienter->SetUseImageDirection(true);
	orienter->SetDesiredCoordinateOrientation(itk::SpatialOrientation::ITK_COORDINATE_ORIENTATION_RPI);

This worked for me!

Hi all!
 
I'm using FEMRegistrationFilter for deformable Registration of 2D images.
I have problems, I couldnt figure otu so far:

1. Are the parameters for the parameter file documented somewhere?

2. A call to

registrationFilter->WriteWarpedImage(outputImageName);

throws

ERROR: Analyze 7.5 File Format Only Allows RPI, PIR, and RIP Orientation
here2Aborted (core dumped)

How can I tackle this problem - I read about the supported image 
orientations, but where and how can I set the orientation for the warped 
image inside FEMRegistrationFilter?

Cheers,

Felix.
