Reassortments involving NA.

The 14 non-terminal, non-pre-terminal RCBs are shown. The table shows the observed and expected distances between the amino acid replacements and the preceding reassortment, and the Wilcoxon p-value for the difference between the observed and expected values. The RCBs are ordered by the Wilcoxon p-value.a Substitutions at phylogenetic distances up to 0.003 ds units after the reassortment.b Phylogenetically independent substitutions are such that none of them are descendant to any of the remaining ones.c Number of substitutions accumulated per lineage.d RCBs also described in [7].e RCBs confirmed by sampling times.
