Hello,

I run SequenceRegistration module on a 4d cardiac CT. As a result i have a sequence of transformations.

I apply the transformations to a segmentation node or to a surface model. How can I save these two as nrrd or VTK for each time instant of the result sequence of transformations ?

Thanks

See a code snippet that does this in the [script repository](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#export-nodes-warped-by-transform-sequence).
