MPBoot is an open-source and efficient program to reconstruct maximum parsimony phylogenetic trees for large DNA and protein sequence alignments. Importantly, MPBoot provides a fast approximation for maximum parsimony bootstrap, inspired by a similar methodology for maximum likelihood (Minh et al., 2013). If you use MPBoot in a paper please cite:
D.T. Hoang, L.S. Vinh, T. Flouri, A. Stamatakis, A. von Haeseler, and B.Q. Minh (2018) MPBoot: fast phylogenetic maximum parsimony tree inference and bootstrap approximation. BMC Evol. Biol., 18, 11. https://doi.org/10.1186/s12862-018-1131-3
For feedback or bug reports please post a question to the IQ-TREE forum:
Precomplied executables are provided for computers with SSE4 or AVX support:
tar xvzf mpboot-avx-1.1.0-Linux.tar.gzunder Unix). This should create a directory
binfolder inside the extracted folder. You can rename it to
mpbootand copy to your system search path such that you can invoke it by entering
mpbootfrom the terminal.
In case you cannot find executables for your platforms or want to compile the source code:
buildin the uncompressed source code folder:
cmake .. -DIQTREE_FLAGS=sse4 -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
avxin above command if you decide to run MPBoot on AVX-supported machines.

Dec 23, 2017 Release
This is the major update of the IQ-TREE software for phylogenomic reconstruction.
IMPORTANT: The checkpoint file is no more compatible with 1.5.X, 1.6.betaX or earlier versions. An error message will be printed if you try to recover the run from old versions. Sequential and multicore versions are merged, thus
iqtree-omp executable becomes
Notable new features:
.model.gzto save space.
-fastto match the speed of FastTree program while still obtaining better trees.
-bnnito further optimize UFBoot trees by nearest neighbor interchange (NNI) directly on corresponding bootstrap alignments (UFBoot2+NNI).
-asrfor ancestral sequence reconstruction written to
-rclusterfto perform fast relaxed clustering algorithm of PartitionFinder2.
-rcluster-maxto limit maximum number of partition pairs for merging with rcluster algorithm.
