Journal ArticleDOI
A simple, fast, and accurate algorithm to estimate large phylogenies by maximum likelihood.
Stéphane Guindon,Olivier Gascuel +1 more
TL;DR: This work has used extensive and realistic computer simulations to show that the topological accuracy of this new method is at least as high as that of the existing maximum-likelihood programs and much higher than the performance of distance-based and parsimony approaches.
Journal ArticleDOI
New Algorithms and Methods to Estimate Maximum-Likelihood Phylogenies: Assessing the Performance of PhyML 3.0
Stéphane Guindon,Jean-François Dufayard,Vincent Lefort,Maria Anisimova,Wim Hordijk,Olivier Gascuel +5 more
TL;DR: A new algorithm to search the tree space with user-defined intensity using subtree pruning and regrafting topological moves and a new test to assess the support of the data for internal branches of a phylogeny are introduced.
Journal ArticleDOI
SeaView Version 4: A Multiplatform Graphical User Interface for Sequence Alignment and Phylogenetic Tree Building
TL;DR: SeaView version 4 combines all the functions of the widely used programs SeaView and Phylo_win, and expands them by adding network access to sequence databases, alignment with arbitrary algorithm, maximum-likelihood tree building with PhyML, and display, printing, and copy-to-clipboard of rooted or unrooted, binary or multifurcating phylogenetic trees.
Journal ArticleDOI
Phylogeny.fr: robust phylogenetic analysis for the non-specialist
Alexis Dereeper,Valentin Guignon,Guillaume Blanc,Stéphane Audic,S. Buffet,François Chevenet,Jean-François Dufayard,Stéphane Guindon,Vincent Lefort,Magali Lescot,Jean-Michel Claverie,Olivier Gascuel +11 more
TL;DR: The Phylogeny.fr platform transparently chains programs to automatically perform phylogenetic analyses and can also meet the needs of specialists; the first ones will find up-to-date tools chained in a phylogeny pipeline to analyze their data in a simple and robust way, while the specialists will be able to easily build and run sophisticated analyses.
Journal ArticleDOI
An Improved General Amino Acid Replacement Matrix
Si Quang Le,Olivier Gascuel +1 more
TL;DR: This method further refine this method by incorporating the variability of evolutionary rates across sites in the matrix estimation and using a much larger and diverse database than BRKALN, which was used to estimate WAG.
