Regular users are probably more interested in installing the precompiled packages. Please see the relevant page on the main MRtrix3 wiki for instructions.

Main usage should take the form:

./run.sh 3.0.8 mrtrix3

Where:

• 3.0.8 is the specific tag or branch to be built
• mrtrix3 is the user or organisation name of the GitHub repo from which to fetch the MRtrix3 source code

This is used to create the installable MRtrix3 package on MSYS2. This will only create the x86-64 version of the package. To use it, clone this repo and invoke the makepkg command within the toplevel folder:

git clone https://github.com/MRtrix3/MinGW.git
cd MinGW/
makepkg

This will generate the package file, which can be installed using this command (edit as appropriate):

pacman -U mingw-w64-x86_64-mrtrix3-3.0_RC3-1-x86_64.pkg.tar.xz
