MRtrix provides a set of tools to perform diffusion-weighted MRI white matter tractography in the presence of crossing fibres, using Constrained Spherical Deconvolution (Tournier et al.. 2004; Tournier et al. 2007), and a probabilisitic streamlines algorithm (Tournier et al., 2012). These applications have been written from scratch in C++, using the functionality provided by the GNU Scientific Library, and Qt. The software is currently capable of handling DICOM, NIfTI and AnalyseAVW image formats, amongst others. The source code is distributed under the GNU General Public License.
This site is under active development - further documentation will be added soon!
- Basic DWI processing
- Anatomically Constrained Tractography (ACT)
- SIFT: Spherical-deconvolution informed filtering of tractograms
- Structural connectome construction
MRtrix should compile and run on any Unix-like system, provided the GNU Scientific Library, Qt (version >= 4.8) and a working implementation of OpenGL (version > 3) are available on that system.
For installation instructions, please refer to the corresponding platform's instructions:
- [GNU/Linux](Installing\ on\ Linux)
- [MS Windows](Installing\ on\ Windows)
- [MacOS X](Installing\ on\ MacOSX)
Support and general discussion is hosted on the MRtrix3 Google+ Community page. Please address all MRtrix3-related queries there. You will need to create a Google+ account if you don't already have one.
Note that issues regarding the previous 0.2.X version of MRtrix should still be addressed to the current NITRC-hosted mailing list.
For development issues and bug reports, please use MRtrix3's issue tracking page on GitHub.
For those interested in contributing to MRtrix3, or just using it as a base to develop their own applications, please consult the Doxygen-generated developer documentation.
If you wish to include results generated using the MRtrix package in a publication, please include a line such as the following to acknowledge this work:
