JF Genome Research JO Genome Research YR 2008 FD January 01 DO 10.1101/gr.073585.107 SP gr.073585.107 UL http://genome.cshlp.org/content/early/2008/11/24/gr.073585.107.abstract AB We have developed a comprehensive gene orientated phylogenetic resource, EnsemblCompara GeneTrees based on a computational pipeline to handle clustering, multiple alignment and tree generation, including the handling of large gene families. We developed two novel non-sequence based metrics of gene tree correctness and benchmarked a number of tree methods. The TreeBeST method from TreeFam shows the best performance in our hands. We also compared this phylogenetic approach to clustering approaches for ortholog prediction, showing a large increase in coverage using the phylogenetic approach. All data is made available in a number of formats and will be kept up to date with the Ensembl project.
