Robinson–foulds rf distance

Webthe RF distance (Robinson and Foulds, 1981), the edges are weighted by 1 (for different clusters) or 0 (for identical clusters). In the b distance (Boorman and Olivier, 1973), which is basically the same as the matching cluster distance of (Bogdanowicz and Giaro, 2012b), each edge is weighted by the size of the symmetric difference of the pair ...

If both trees are unrooted and binary this value is 2 n − 6. WebThe Robinson-Foulds (RF) metric is arguably the most widely used measure of phylogenetic tree similarity, despite its well-known shortcomings: For example, moving a single taxon in a tree can result in a tree that has maximum distance to the original one; but the two trees are identical if we remove the single taxon. To this end, we propose a ... darnall charter school website

WebThe Robinson-Foulds (RF or ‘partition’) metric (Robinson & Foulds, 1981; Steel & Penny, 1993) measures the symmetric difference between two trees by adding the number of splits (i.e. groupings) that are present in tree A (but not tree B) to the number of splits present in tree B (but not tree A).

WebPairwise tree similarities were estimated using Robinson–Foulds (RF) distances , both absolute and normalized to the maximum possible distance.
