Can Shapework calculate PCA Component Scores in new cases without rebuilding a new model？

[amorris]

Yes, this can be accomplished by using the “fixed_domans” feature. An example is provided here:

Fixed Domains Ellipsoid: Shape Model on New Shapes - ShapeWorks

Essentially, you do re-run the optimization, but your original shapes are held constant (fixed), allowing the new shapes to conform to the existing shape model.

Easiest way to enable fixed column within shapeworks studio?

The option is not exposed in Studio since it is a fairly advanced feature. We will add it though. It should still work as long as it’s in the spreadsheet. You may be missing the “use_fixed_subjects” option though. Try this: "use_fixed_subjects": "1", "fixed_subjects_column": "fixed", "fixed_subjects_choice": "yes"
