Reflect markups (landmarks)

Dear list, I’m placing markups (landmarks) to carry out a geometric morphometric analysis in some mammals skulls. I have some cases where one of the zygomatic archs is missing (screen capture below). Is there a way to reflect one side markups based on a defined plane to estimate landmarks of the missing structure (in this case the right zygomatic arch).
Kind regards,


Currently there is no automated (or UI driven) way of doing it. You will have to define the symmetry plane (Markups->Plane tool) and then the position of the LM can be reflected using that particular plane.

I wrote a function that does this in Python here. It does a few extra things (merges points that are very close to the symmetry plane, creates a left, right and merged landmark set) so it would need to be altered a little bit. The plane needs to be defined or calculated before using this function, as @muratmaga noted.
