Bootstrapping phylogenies inferred from rearrangement data

Background: Large-scale sequencing of genomes has enabled the inference of phylogenies based on the evolution of genomic architecture, under such events as rearrangements, duplications, and losses. Many evolutionary models and associated algorithms have be ...

Reconstruction of Large-Scale Phylogenies : Advances in Algorithms and Statistical Methods

Vaibhav Rajan

The evolutionary relationships between organisms or phylogenies are fundamental to biology. They are invaluable as guiding tools to mine, organize and exploit the enormous amounts of biological data in the post-genomic era. The advent of high-throughput se ...

A Metric for Phylogenetic Trees Based on Matching

Bernard Moret, Yu Lin, Vaibhav Rajan

Comparing two or more phylogenetic trees is a fundamental task in computational biology. The simplest outcome of such a comparison is a pairwise measure of similarity, dissimilarity, or distance. A large number of such measures have been proposed, but so f ...

TIBA: a tool for phylogeny inference from rearrangement data with bootstrap analysis

Bernard Moret, Yu Lin, Vaibhav Rajan

TIBA is a tool to reconstruct phylogenetic trees from rearrangement data that consist of ordered lists of synteny blocks (or genes), where each synteny block is shared with all of its homologues in the input genomes. The evolution of these synteny blocks, ...

Fast and accurate phylogenetic reconstruction from high-resolution whole-genome data and a novel robustness estimator

Bernard Moret, Yu Lin, Vaibhav Rajan

The rapid accumulation of whole-genome data has renewed interest in the study of genomic rearrangements. Comparative genomics, evolutionary biology, and cancer research all require models and algorithms to elucidate the mechanisms, history, and consequence ...

Sorting signed permutations by inversions in O(nlogn) time

Bernard Moret, Yu Lin, Vaibhav Rajan, Krister Swenson

The study of genomic inversions (or reversals) has been a mainstay of computational genomics for nearly 20 years. After the initial breakthrough of Hannenhalli and Pevzner, who gave the first polynomial-time algorithm for sorting signed permutations by inv ...
