How do I run RAxML on Windows?
Just download the zip file from Github ( https://github.com/stamatak/standard-RAxML ) and unpack it. Then open a command prompt window, go to the \standard-RAxML-master\WindowsExecutables_v8. 2.4 directory, and execute the program.
What does RAxML do?
RAxML (Randomized Axelerated Maximum Likelihood) is a program for sequential and parallel Maximum Likelihood based inference of large phylogenetic trees. It can also be used for post- analyses of sets of phylogenetic trees, analyses of alignments and, evolutionary placement of short reads.
How long does RAxML take?
3): RAxML was the slowest, taking between 647 and 2150 hours to produce trees, FastTree the fastest, taking between 2 and 6.3 hours, and RAxML-Limited in between, taking between 10 and 50 hours.
How do you use RAxML?

What is the Gtrgamma model?
– -m GTRGAMMA: GTR model of nucleotide substitution with the Γ model of rate heterogeneity. All model parameters are estimated by RAxML. The GTRGAMMA implementation uses 4 discrete rate categories which repre- sents an acceptable trade-off between speed and accuracy.
What is RAxML Ng?
RAxML-NG is a phylogenetic tree inference tool which uses maximum-likelihood (ML) optimality criterion. Its search heuristic is based on iteratively performing a series of Subtree Pruning and Regrafting (SPR) moves, which allows to quickly navigate to the best-known ML tree.
What is Kimura model?
The Kimura two-parameter (K2P) model (Kimura 1980) is probably the most widely used of all models of nucleotide substitution for estimating genetic differences (generally called genetic distances) and phylogenetic relationships.
What is Hasegawa kishino Yano model?
The Hasegawa-Kishino-Yano (HKY) 1985 Substitution Model. The Jukes-Cantor model assumes that all substitution rates are equal, which also implies that the stationary frequencies of the four nucleotide bases are equal.
How do you cite RAxML?
When using RAxML please cite the following paper: A. Stamatakis: “RAxML Version 8: A tool for Phylogenetic Analysis and Post-Analysis of Large Phylogenies”. In Bioinformatics, 2014, open access.
What is Kimura 2 parameter distance?
Kimura’s two parameter model (1980) corrects for multiple hits, taking into account transitional and transversional substitution rates, while assuming that the four nucleotide frequencies are the same and that rates of substitution do not vary among sites (see related Gamma distance).
What is K2P distance?
2.2. The K2P distance is the most effective model when genetic distances are low [12]. Interspecific K2P distances were calculated for those species with at least two sequences, and intraspecific K2P distances were calculated between species in the entire data set.
What is GTR model?
The GTR model is a stationary Markov process by which substitution probabilities among nucleotides are expressed in the form of a matrix P(t). The GTR model assumes that the equilibrium character state frequencies and the instantaneous transition probabilities remain constant through time.
What can phylogenetic trees tell us?
A phylogenetic tree can help trace a species back through evolutionary history, down the branches of the tree, and locate their common ancestry along the way. Over time, a lineage may retain some of their ancestral features but will also be modified to adapt to the changing environment.
What does a phylogenetic tree show?
A phylogenetic tree, also known as a phylogeny, is a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor.
How do I display bootstrap values in Figtree?
Open the Newick text file using the File -> Open menu within Figtree. When prompted, change the name “label” to “bootstrap.” Bootstrap values can be found in the pull-down menu under the Figtree tab “Node Labels.”
