bookmark RANGER-DTL / Rapid ANalysis of Gene family Evolution using Reconciliation-DTL Infers gene family evolution by speciation, gene duplication, horizontal gene transfer, and gene loss. RANGER-DTL consists of ten related programs designed to work together to support various reconciliation analyses. It enables the use of reconciliation-based gene tree and species tree reconstruction methods for prokaryotes. It permits analysis of gene families and offers several advanced features. It can also analyze trees with thousands of taxa.
