||P.5 right column bottom paragraph: "Table 1 provides a natural partitioning of the data presented in Fig. 5 (BNID 113166). Although double-stranded viruses have, in average, only half the volume usage of single-stranded viruses (24 % instead of 49 %), both lack a correlation between volume usage and genome length. [Investigators] further tested the sensitivity of the calculation towards families with segmented viruses. When repeating the analysis with the exclusion of all segmented viruses (ending up with 18 families instead of 24), [they] observed only a minor effect on [their] global analysis (not shown)." P.10 left column top paragraph: "The observation that the volume usage of single-stranded viruses is significantly higher than that of double-stranded (49 % vs. 24 % on average, Table 1) remains unexplained. However, in some families the viruses are packed with additional proteins that are essential for the infectivity (e.g., Vif protein in HIV [ref 62])."
