Results of the t-Tests Performed in Fig. 6

	Vector	E_loc	t(41)	p-value

PCA	1	0.322715	10.5302	4.667609e-07
	3	0.175157	6.3989	6.336324e-05
	11	0.223596	−5.7523	1.576577e-04

Symmetric LoCA	1	0.0888693	10.2211	2.324091e-06
	11	0.00808553	7.1989	2.204578e-05
	8	0.0179966	6.763	3.088845e-04

The shown p-values are Bonferroni-corrected. Note that the Symmetric LoCA vectors are both local and find statistically-significant differences between the branching groups.
