iqtree3 3.1.4+dfsg-1

Package Information

Descriptionefficient phylogenetic software by maximum likelihood; v3

The IQ-TREE software was created as the successor of IQPNNI and TREE-PUZZLE (thus the name IQ-TREE). IQ-TREE was motivated by the rapid accumulation of phylogenomic data, leading to a need for efficient phylogenomic software that can handle a large amount of data and provide more complex models of sequence evolution. To this end, IQ-TREE can utilize multicore computers and distributed parallel computing to speed up the analysis. IQ-TREE automatically performs checkpointing to resume an interrupted analysis.

As input IQ-TREE accepts all common sequence alignment formats including PHYLIP, FASTA, Nexus, Clustal and MSF. As output IQ-TREE will write a self-readable report file (name suffix .iqtree), a NEWICK tree file (.treefile) which can be visualized by tree viewer programs such as FigTree, Dendroscope or iTOL.

Key features of IQ-TREE

- Efficient search algorithm: Fast and effective stochastic algorithm to reconstruct phylogenetic trees by maximum likelihood. IQ-TREE compares favorably to RAxML and PhyML in terms of likelihood while requiring similar amount of computing time (Nguyen et al., 2015). - Ultrafast bootstrap: An ultrafast bootstrap approximation (UFBoot) to assess branch supports. UFBoot is 10 to 40 times faster than RAxML rapid bootstrap and obtains less biased support values (Minh et al., 2013). - Accurate model selection: An ultrafast and automatic model selection (ModelFinder) which is 10 to 100 times faster than jModelTest and ProtTest. ModelFinder also finds best-fit partitioning scheme like PartitionFinder (Kalyaanamoorthy et al., 2017). - Alignment simulation: A flexible simulator (AliSim) which allows to simulate sequence alignments under more realistic models than Seq-Gen and INDELible (Ly-Trong et al., 2023). - Phylogenetic testing: Several fast branch tests like SH-aLRT and aBayes test (Anisimova et al., 2011) and tree topology tests like the approximately unbiased (AU) test (Shimodaira, 2002).

The strength of IQ-TREE is the availability of a wide variety of phylogenetic models:

- Common models: All common substitution models for DNA, protein, codon, binary and morphological data with rate heterogeneity among sites and ascertainment bias correction for e.g. SNP data. - Partition models: Allowing individual models for different genomic loci (e.g. genes or codon positions), mixed data types, mixed rate heterogeneity types, linked or unlinked branch lengths between partitions. - Mixture Models: fully customizable mixture models and empirical protein mixture models and. - Polymorphism-aware models (PoMo) http://www.iqtree.org/doc/Polymorphism-Aware-Models

Changelog
iqtree3 (3.1.4+dfsg-1) unstable; urgency=medium
 .
   * New upstream version
   * Simplify watch file
   * Drop 'Rules-Requires-Root: no' from d/control (routine-update)
   * New Build-Depends: libcmaple-dev, liblsd2-dev
   * Deactivate help2man created manpages
   * Build shared libiqtree.so.<SOVERSION> library and provide
     new binary packages libiqtree3 and libiqtree-dev so that
     python-cogent/piqtree can link against IQ-TREE
   * Make build reproducible by deriving the embedded build date from
     SOURCE_DATE_EPOCH instead of the __DATE__ macro
   * Make build reproducible by disabling -march=native in the
     terraphast sub-library, which otherwise makes the binaries depend
     on the CPU of the build machine
   * Remove binaries for several architectures in test_scripts/iqtree2
