WebBootstrap Test of Phylogeny. One of the most commonly used tests of the reliability of an inferred tree is Felsenstein's (1985) bootstrap test, which is evaluated using Efron's (1982) bootstrap resampling technique.

WebThis shows that the length of the shortest tree is 4942. To find Bremer support values we need to retain more trees than just the most parsimonious tree. If the shortest tree in your search was 4942, to find which nodes have a decay index of 1, you need to find all the trees with 4943 steps or less. To do this we will use the keep option.
