If the authors don’t respond for very long time then you can do the computations with a little bit of Python scripting. You can get the displacement field from the transform node and use [ITK-strain Python package](https://pypi.org/project/itk-strain/) to compute the strain. You can use the strain to color segmented surfaces (using `Probe volume with model` module) or compute statistics in selected image regions (using `Segment Statistics` module).
