Hello is there a way to extract the translation data only from a transform matrix. I have a transform between two scans but I only need to see the translation. How do I do this? Thank you.
The translation is just the first three rows of the last column of the 4x4 matrix.
I cannot find the transformation matrix. I used ElastiX to register two different frames.
Usually the matrix just shows up in the transforms module but it is not there?
Unfortunately, from Elastix we can only get a displacement field from Elastix. Either Elastix would need to be improved to save transform in standard ITK file format (https://github.com/SuperElastix/elastix/issues/18) or SlicerElastix module would need to be improved to be able to parse Elastix proprietary transform file format.
No problem and thank you for the clarification! I can still play around with the displacement field for my purposes.
