Rooting human parechovirus evolution in time

Table 1 Statistical parameters estimates from BEAST analysis under a strict and relaxed molecular clock

Genetic region	Molecular clock	Coefficient of variation (σ_r)	Prior Probability^a	Marginal Posterior^a
P1	Strict	-	-183.8 (199.6, 167.4)	-23989 (24007, 23971)
	Lognormal	0.29	-180 (154, 216)	-23968 (24003, 23934)
VP1	Strict	-	-1407 (1457, 1350)	-19148 (19208, 19094)
	Lognormal	0.41	-1362 (1433, 1301)	-19033 (19103, 18964)

^aMean prior and marginal posterior probabilities for both clock models are given with 95% lower and upper bounds of the highest probability density intervals in parentheses. The coefficient of variation is a measure of the rate variation among branches (see Methods for details).
