a Data processing workflow for clustering the models based on the deformed shape of the inner panels. Five different clusters were produced by k-Means clustering of the principal components of the B-spline coefficients fitted to the z-coordinates. b–f Representative examples of the final shapes of the centerline of the central panel for the black, yellow, blue, green, and red clusters, respectively shown in the scatter plot in a.
