Parallel Inference of a 10.000-Taxon Phylogeny with Maximum Likelihood
Inference of large phylogenetic trees with statistical methods is computationally intensive. We recently introduced simple heuristics which yield accurate trees for synthetic as well as real data and are implemented in a sequential program called RAxML. We have demonstrated that RAxML outperforms the currently fastest statistical phylogeny programs (MrBayes, PHYML) in terms of speed and likelih...
متن کاملGenetic algorithms and parallel processing in maximum-likelihood phylogeny inference.
We investigated the usefulness of a parallel genetic algorithm for phylogenetic inference under the maximum-likelihood (ML) optimality criterion. Parallelization was accomplished by assigning each "individual" in the genetic algorithm "population" to a separate processor so that the number of processors used was equal to the size of the evolving population (plus one additional processor for the...
متن کاملCorrecting for Sequencing Error in Maximum Likelihood Phylogeny Inference
Accurate phylogenies are critical to taxonomy as well as studies of speciation processes and other evolutionary patterns. Accurate branch lengths in phylogenies are critical for dating and rate measurements. Such accuracy may be jeopardized by unacknowledged sequencing error. We use simulated data to test a correction for DNA sequencing error in maximum likelihood phylogeny inference. Over a wi...
متن کاملDPRml: distributed phylogeny reconstruction by maximum likelihood
MOTIVATION In recent years there has been increased interest in producing large and accurate phylogenetic trees using statistical approaches. However for a large number of taxa, it is not feasible to construct large and accurate trees using only a single processor. A number of specialized parallel programs have been produced in an attempt to address the huge computational requirements of maximu...
متن کاملFast Parallel Maximum Likelihood-Based Protein Phylogeny
Inferring phylogenetic relationships between sequences is a difficult and interesting problem. Assuming that there is enough phylogenetic signal in biological sequence to resolve every tree bifurcation, the resulting tree is a representation of the vertical descent history of a gene. A popular method to evaluate a candidate phylogenetic tree uses the likelihood of the data, given an empirical m...
