A Novel Approach for Compressing Phylogenetic Trees [chapter]

Suzanne J. Matthews, Seung-Jin Sul, Tiffani L. Williams
2010 Lecture Notes in Computer Science  
We introduce TreeZip, a novel algorithm to compress phylogenetic trees based on their shared evolutionary relationships.  ...  Our results strongly suggest that TreeZip is very effective at compressing phylogenetic trees, which allows for easier exchange of data with colleagues around the world.  ...  Acknowledgments Funding for this project was supported by NSF under grants DEB-0629849 and IIS-0713618.  ...

Abstract.  ...  An approach of building phylogenetic trees is to define a distance function based on amino acid sequences of distinct proteins.  ...  We would also like to build a number of tree topologies at the same time in order to cover a greater part of the solution space.  ...

Alignment-free analysis of barcode sequences by means of compression-based methods

Massimo La Rosa, Antonino Fiannaca, Riccardo Rizzo, Alfonso Urso
2013 BMC Bioinformatics  
We built phylogenetic trees of every dataset, according to compression-based and classic evolutionary methods, and compared them in terms of topology preservation.  ...  In the experimental tests, we obtained scores with a percentage of similarity between evolutionary and compression-based trees between 80% and 100% for the most of datasets (94%).  ...  Declarations The publication costs for this article were funded by the CNR Interomics Flagship Project "-Development of an integrated platform for the application of "omic" sciences to biomarker definition  ...

Prophyle: A Phylogeny-Based Metagenomic Classifier Using The Burrows-Wheeler Transform

Karel Břinda, Kamil Salikhov, Simone Pignotti, Gregory Kucherov
2017 Zenodo  
Overall, ProPhyle provides an index for resource-frugal metagenomic classification, which is accurate even with single-species phylogenetic trees.  ...  The aim of metagenomic classification is to assign each sequence of the metagenome to a corresponding taxonomic unit, or to classify it as "novel".  ...  This problem appears, in particular, with phylogenetic trees for a single species. Therefore, our objective is to store a list of associated nodes for every k-mer.  ...

Missing the Forest for the Trees: Phylogenetic Compression and Its Implications for Inferring Complex Evolutionary Histories

Cécile Ané, Michael J. Sanderson, Mike Steel
2005 Systematic Biology  
We show not only that phylogenetic compression is an efficient method for encoding most phylogenetic data sets and is more efficient than compression schemes designed for single sequences, but also that  ...  it provides a clear information theoretic rule for determining when a collection of conflicting trees is a better explanation of the data than a single tree.  ...  Eulenstein, and Raul Piaggio for discussion of these issues, and Mike Steel, Ming Li, and an anonymous reviewer for helpful comments.  ...

Information Theoretic Approaches to Whole Genome Phylogenies [chapter]

David Burstein, Igor Ulitsky, Tamir Tuller, Benny Chor
2005 Lecture Notes in Computer Science  
We describe a novel method for efficient reconstruction of phylogenetic trees, based on sequences of whole genomes or proteomes, whose lengths may greatly vary.  ...  We describe here five different applications of the method, which not only show the validity of the method, but also suggest a number of novel phylogenetic insights.  ...  Acknowledgements We would like to thanks Eran Bacharach, Tal Pupko, and Jacob Ziv for helpful discussions.  ...

Whole-genome prokaryotic clustering based on gene lengths

A. Bolshoy, Z. Volkovich
2009 Discrete Applied Mathematics  
The fast-growing number of complete genome sequences prompts the development of new phylogenetic approaches.  ...  This approach is not a regular distance-based method, distinguishing it from other recently published wholegenome based clustering techniques.  ...  Acknowledgement We wish to thank Valery Kirzhner for the interest in the study and for the helpful discussions.  ...
