BranchClust: a phylogenetic algorithm for selecting gene families.

ABSTRACT:

Background

Automated methods for assembling families of orthologous genes include those based on sequence similarity scores and those based on phylogenetic approaches. The first are easy to automate but usually they do not distinguish between paralogs and orthologs or have restriction on the number of taxa. Phylogenetic methods often are based on reconciliation of a gene tree with a known rooted species tree; a limitation of this approach, especially in case of prokaryotes, is that the species tree is often unknown, and that from the analyses of single gene families the branching order between related organisms frequently is unresolved.

Results

Here we describe an algorithm for the automated selection of orthologous genes that recognizes orthologous genes from different spec
