Fig. 5From: Fast ancestral gene order reconstruction of genomes with unequal gene contentTo find adjacency weights for node α on a tree T, a new tree T ′ is created where α and its subtree T1 are removed, and T ′ is rerooted at γ, the parent node of α. Then, Eq. (4) is applied to find weights for γ, which are then assigned to node α on the original tree T Back to article page
