Abstract
This article presents W-IQ-TREE, an intuitive and user-friendly web interface and server for IQ-TREE, an efficient phylogenetic software for maximum likelihood analysis. W-IQ-TREE supports multiple sequence types (DNA, protein, codon, binary and morphology) in common alignment formats and a wide range of evolutionary models including mixture and partition models. W-IQ-TREE performs fast model selection, partition scheme finding, efficient tree reconstruction, ultrafast bootstrapping, branch tests, and tree topology tests. All computations are conducted on a dedicated computer cluster and the users receive the results via URL or email. W-IQ-TREE is available at http://iqtree.cibiv.univie.ac.at. It is free and open to all users and there is no login requirement.
Highlights
IQ-TREE [1], the successor of the TREE-PUZZLE program [2], is an efficient and versatile phylogenetic software for maximum likelihood analysis of large phylogenetic data
W-IQ-TREE currently runs on a computer cluster with 32 CPUs, which can be extended depending on the usage
It provides a web interface to interact with users and send user requests to the computer cluster, where the actual computation is done with the most recent sequential IQ-TREE version
Summary
IQ-TREE [1], the successor of the TREE-PUZZLE program [2], is an efficient and versatile phylogenetic software for maximum likelihood analysis of large phylogenetic data. Many web applications with intuitive user-interface were developed We present W-IQ-TREE, a user-friendly web application and compute server for phylogenetic analyses with the IQ-TREE software. Since its first launch in April 2014 the numbers of users and submitted jobs are steadily increasing (Figure 1). This is most likely attributed to the user-friendly features presented below. It provides a web interface to interact with users and send user requests to the computer cluster, where the actual computation is done with the most recent sequential IQ-TREE version. We describe important elements of the web interface
