Fasttree

DESCRIPTION

    FastTree infers approximately-maximum-likelihood phylogenetic trees from
    alignments of nucleotide or protein sequences. FastTree can handle alignments
    with up to a million of sequences in a reasonable amount of time and memory.
    For large alignments, FastTree is 100-1,000 times faster than PhyML 3.0 or RAxML 7.

    FastTree is more accurate than PhyML 3 with default settings, and much more accurate
    than the distance-matrix methods that are traditionally used for large alignments.
    FastTree uses the Jukes-Cantor or generalized time-reversible (GTR) models of
    nucleotide evolution and the JTT (Jones-Taylor-Thornton 1992), WAG (Whelan & Goldman 2001),
    or LG (Le and Gascuel 2008) models of amino acid evolution.
    To account for the varying rates of evolution across sites,
    FastTree uses a single rate for each site (the "CAT" approximation).
    To quickly estimate the reliability of each split in the tree, FastTree computes
    local support values with the Shimodaira-Hasegawa test (these are the
    same as PhyML 3's "SH-like local supports").
