ArboDraw is a program for building and displaying phylogenetic trees of protein and nucleic acid sequences. It can import and display dendrogram files in Newick format (generated by MUSCLE, Phylip, clustalw, etc.). Among the key features are the ability to annotate sequences, and to select and color independently various parts of the tree. A very convenient annotation functionality allows the user to view annotations by placing the mouse above the sequence of interest. Edited and annotated files can be saved and restored at a later time.
CONSEL is a program package consists of small programs written in C language. It calculates the probability value (i.e., p-value) to assess the confidence in the selection problem. Although CONSEL is applicable to any selection problem, it is mainly designed for the phylogenetic tree selection. CONSEL does not estimate the phylogenetic tree by itself, but CONSEL does read the output of the other phylogenetic packages, such as Molphy, PAML, PAUP*, TREE-PUZZLE, and PhyML. CONSEL calculates the p-value using several testing procedures; the bootstrap probability, the Kishino-Hasegawa test, the Shimodaira-Hasegawa test, and the weighted Shimodaira-Hasegawa test. In addition to these conventional tests, CONSEL calculates the p-value based on the approximately unbiased test using the multi-scale bootstrap technique.
Baobab is an editor for large phylogenetic trees written in Java. It allows you to create and/or modify a tree interactively, adding/(re)moving branches and nodes, changing leave names, setting parameters. Baobab focuses on edition, not representation and display that are only used as a tool to make edition easier.
NJplot is a tree drawing program able to draw any phylogenetic tree expressed in the Newick phylogenetic tree format (e.g., the format used by the PHYLIP package). NJplot is especially convenient for rooting the unrooted trees obtained from parsimony, distance or maximum likelihood tree-building methods.
Unrooted is a tree drawing program able to draw any binary tree expressed in the standard phylogenetic tree format (e.g., the format used by the PHYLIP package). Trees are drawn in an unrooted way, that is, using a circular shape, with labels aligned with terminal branches.
Treevolution is a Java tool for the representation and exploration of phylogenetic trees that facilitates visual analysis. There are several useful tools to visualize phylogenetic trees, but their level of interaction is usually low, especially in the case of radial representations. Highly interactive visualizations can improve the exploration and understanding of phylogenetic trees. Treevolution implements strategies to interact with phylogenetic trees in order to allow a more thorough analysis by users.
Ktreedist is a computer program written in Perl that calculates the minimum branch length distance from one phylogenetic tree to another, providing a measure of the difference in topology and relative branch lengths (shape) between two trees
SICLE (Sister Clade Extractor) is an easy to use, adaptable, and high-throughput tool to describe the nearest neighbors to a node of interest in a phylogenetic tree as well as the support value for the relationship.
SSA is a program for inferring maximum likelihood phylogenies from DNA sequences. Two versions of the program are available: one which assumes a molecular clock and one which does not make this assumption. The method for searching the space of trees for the ML tree is based on a simulated-annealing type algorithm and is described in the reference above. The program implements Felsenstein’s F84 model of nucleotide substitution and associated sub-models. The program estimates the ML tree and branch lengths, and can optionally estimate the transversion/transversion ratio. Upon termination, the program returns the k trees of highest likelihood found during the search, where k can be set by the user.
