IQ-TREE 2: New models and efficient methods for phylogenetic inference in the genomic era

Abstract

Abstract IQ-TREE ( http://www.iqtree.org ) is a user-friendly and widely used software package for phylogenetic inference using maximum likelihood. Since the release of version 1 in 2014, we have continuously expanded IQ-TREE to integrate a plethora of new models of sequence evolution and efficient computational approaches of phylogenetic inference to deal with genomic data. Here, we describe notable features of IQ-TREE version 2 and highlight the key advantages over other software.
