Please also look through the Frequently Asked Questions on the wiki section of the forum. You can address all MRtrix3-related queries there, using your GitHub or Google login to post questions.

Quick install

  1. Install dependencies by whichever means your system uses. These include: Python (>=2.6), a C++ compiler with full C++11 support (g++ 4.9 or later, clang++), Eigen (>=3.2.8), zlib, OpenGL (>=3.3), and Qt (>=4.8, or at least 5.1 on MacOSX).

  2. Clone Git repository and compile:

     $ git clone https://github.com/MRtrix3/mrtrix3.git
     $ cd mrtrix3/
     $ ./configure
     $ ./build
    
  3. Set the PATH:

    • Bash shell:

      run the set_path script provided:

        $ ./set_path
      

      or edit the startup ~/.bashrc or /etc/bash.bashrc file manually by adding this line:

        $ export PATH=/<edit as appropriate>/mrtrix3/bin:$PATH
      
    • C shell:

      edit the startup ~/.cshrc or /etc/csh.cshrc file manually by adding this line:

        $ setenv PATH /<edit as appropriate>/mrtrix3/bin:$PATH
      
  4. Test installation:

    Command-line:

     $ mrconvert
    

    GUI:

     $ mrview
    

Keeping MRtrix3 up to date

  1. You can update your installation at any time by opening a terminal in the mrtrix3 folder, and typing:

     git pull
     ./build
    
  2. If this doesn't work immediately, it may be that you need to re-run the configure script:

     ./configure
    

    and re-run step 1 again.

Building a specific release of MRtrix3

You can build a particular release of MRtrix3 by checking out the corresponding tag, and using the same procedure as above to build it:
