Tractography.jl
This Julia package aims at tractography by taking advantage of parallel and specific hardwares (e.g. GPU). Tractography aims at reconstructing white matter fiber bundles using diffusion-weighted MRI. It thus aim to study the structural connectivity of the brain.
π¦ Installation
Assuming that you already have Julia correctly installed, it suffices to import Tractography.jl in the standard way:
import Pkg; Pkg.add("Tractography")

π§βπ» Other softwares
Similar algorithms as the one provided here are implemented in the python package
https://gitlab.inria.fr/cronos/software/tractography
There are several good softwares already available.
- DIPY
- DSI-studio
- Entrack
- ExploreDTI
- Fibers.jl julia set of tools to deal with diffusion MRI data.
- MRtrix the main software to perform, among other things, tractography. It lacks GPU capability though.
- Microstructure.jl
- Scilpy
- Trekker
In Julia, the present package seems to be the only one focused on tractography.
A word on performance
The examples which follow have not all been written with the goal of performance but rather simplicity.
However, note that this code was used to sample 500 000 000 000 streamlines on GPU for a recent publication.
