fasttree - 2.1.10-2 main

FastTree infers approximately-maximum-likelihood phylogenetic trees from
alignments of nucleotide or protein sequences. It handles 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) model 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").

This package contains a single threaded version (fasttree) and a
parallel version which uses OpenMP (fasttreMP).
