ModelTest-NG is a tool for selecting the best-fit model of evolution for DNA and protein alignments. ModelTest-NG supersedes jModelTest and ProtTest in one single tool, with graphical and command console interfaces.

If you want to read about using ModelTest-NG, a PDF manual is attached to each release. You can also browse the wiki for online documentation, and the FAQ section for common errors.

From the releases section you can download the latest stable distribution and pre-compiled binaries.

If there is no binary for your system or it is not working, you can either download the sources distribution or clone this repository, and follow the Install instructions below:

$ git clone https://github.com/ddarriba/modeltest

1. Install the dependencies. On Debian-based systems, you can simply run

sudo apt-get install flex bison

For other systems, please make sure you have following packages/libraries installed: GNU Bison Flex

2. Build ModelTest-NG.

Multithread version:

mkdir build && cd build
cmake ..
make

MPI version:

mkdir build && cd build
cmake -DENABLE_MPI=ON ..
make

GUI version:

mkdir build && cd build
cmake -DENABLE_GUI=ON ..
make

Portable version (static linkage, compatible with old non-AVX CPUs):

mkdir build && cd build
cmake -DSTATIC_BUILD=ON -DENABLE_MODELTEST_SIMD=OFF -DENABLE_PLLMOD_SIMD=OFF ..
make

ModelTest-NG binaries will be placed in modeltest-ng/bin directory.

If you want to build a Docker image, use a command like this:

docker build -t modeltest-ng .

Then call docker run to create a container using the created image.

docker run -it modeltest-ng bash
