Bioinformatics phylogenetic tree
WebJan 21, 2014 · PHYLOGENETICS 1 INTRODUCTION RAxML (Randomized Axelerated Maximum Likelihood) is a popular program for phylogenetic analysis of large datasets under maximum likelihood. Its major strength is a fast maximum likelihood tree search algorithm that returns trees with good likelihood scores. WebSometimes asterisks (*) are used instead to indicate branches where there is greater than 80% (or 90%) bootstrap support, as shown in the right-hand tree in Figure 11. In this example, the bootstrap value of 63 out of 100 (63%) is not represented by an asterisk because it is less than 80% support. Interpreting confidence estimates on a tree
