Procrustes transforms missing from multi-level PCA analysis #2134

Closed akenmorris closed 11 months ago

The procrustes transforms seem to be discarded when using the newer multi-level PCA. Running a toy example of dual spheres of changing radii with procrustes should show spheres of equal size at all times:

Input data:

Using ShapeWorks 6.3.2 before the multi-level PCA was introduces, the sphere’s all appear the same size (procrustes scaling was on):

In the current and I assume 6.4 release, the first mode of variation shows the spheres changing size as if procrustes scaling was off.
