Relevant morphometrics for the NBC type. Left: per-type boxplots for the nine morphometrics selected with RF BVI (RF BVI values shown, in blue, to the right). For most NBC cells, the axon never arborized far from the soma (low euclidean_dist.max; top part of the panel) nor outside of its cortical layer (low translaminar). Although selected by RF BVI, length.avg and density_bifs, the box-plots (bottom part) show that these morphometrics were not univariately useful. Right: the nine selected morphometrics separate the NBC cells from non-NBC ones. The biplot shows the data projected onto the two principal components, found with principal component analysis, with the vectors representing the morphometrics and the angles between them indicative of their pairwise correlation. Besides branch length (length.avg), translaminar reach (translaminar), and arborization density (density_bifs), all selected morphometrics are related to arborization distance from soma. They correspond to the vectors pointing towards the right; only euclidean_dist.avg is annotated to avoid overlapping
