Geometric Morphometrics with Slicermorph

The Slicermorph extension for 3D Slicer includes tools for the preliminary steps of geometric morphometrics (GMM), including the Generalized Procrustes Analysis on 3D landmarks and visualization of the shape space. The dataset used in this video will be made available once my paper is published.
