CART model (F-measure value of 0.85) for BA derived from the six morphometrics selected with RF BVI. Most of the BA cells (i.e., those contained in the two rightmost tree leaves) have a path_dist.avg <414 and either y_mean_abs <133 or remote_bifurcation_angle.avg <75°, meaning that they arborize close to the soma, especially vertically, whereas if they do arborize further vertically (as some LBC cells do), they have sharper bifurcation angles. Each box represents a split in the data set, indicating: (a) its majority type (BA is the majority type overall and hence it is shown in the root node of the tree (i.e., the initial split)); (b) proportion of positive examples (BA cells represent 57% of the data set and hence 0.57 in the root node; they present 95% of the samples in the rightmost node); and (c) the percentage of the data set reaching the split (100% of the data passes through the root split; 44% of the data set reaches the rightmost node)
