Download Links: “Hou” versions (2024-)
Hou version is currently at the pre-release stage under frequent updates and testing
Download and unzip to run the executive. No installation is needed. DSI Studio has a high version turning rate, and the computation outcome may differ between versions. I would recommend keeping a local copy of DSI Studio for each research project and updating DSI Studio every time a new project is initiated.
| OS | File | Note |
|---|---|---|
| Windows (7+) | GPU version (needs a NVIDIA graphic card) CPU version |
Unzip the file and click on the DSI Studio program to run it. If missing DLL files, install the VC package. To use GPU, install CUDA Toolkit and update your graphic drivers. |
| Mac (13+) | dsi_studio_mac-15.zip dsi_studio_mac-14.zip dsi_studio_mac-13.zip |
make sure to enable run permission. On MacOS 15, the system may show the app is damaged because it is not notarized (requires $99 per year). To bypass Gatekeeper, run the line below in the terminal: xattr -rd com.apple.quarantine /path/to/dsi_studio.app. |
| Ubuntu (20.04+) | GPU versions (need a NVIDIA graphic card): dsi_studio_ubuntu2004.zip dsi_studio_ubuntu2204.zip dsi_studio_ubuntu2404.zip CPU versions: dsi_studio_ubuntu2004_cpu.zip dsi_studio_ubuntu2204_cpu.zip dsi_studio_ubuntu2404_cpu.zip |
If showing error related to libQt6Charts, run sudo apt install libqt6charts6-devIf reporting error related to xcb, check out this solution. |
| CentOS 8 | dsi_studio_centos8.zip | |
| Container (Docker) | docker hub repository: dsistudio/dsistudio:latest |
docker run -ti --rm -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix -v $PWD:/data dsistudio/dsistudio:latest |
Unique in Hou versions
- 2024/08:
- New FIB/SRC format (.fz,.sz): higher storage efficiency.
- DSI Studio Data Hub: instant access to thousands of readily trackable data.
- New linear and nonlinear registrations: support simultaneously multi-modality registration with greater accuracy dealing with lesions.
- New GUI
Previous Versions
Major Changes
- 2020/08/02: Major revision on QA calculation. nQA is now replacing QA (https://groups.google.com/g/dsi-studio/c/t-kSFxXrGFU)
- 2023/06/28: Fiber tracking results will change because the default step size = 0 has a different implementation. Older versions will randomly select between 0.5 and 1.5 voxel spacing. The updated version will have 1.0 voxel spacing. To replicate older versions, set the step size to -1 in the command line. Fiber tracking with nonzero step size and correlation tracking is not affected.
- 2023/07/08: Tractography atlas is further separated into 5 sets of pathways. The GUI and command line interface for automated fiber tracking has been modified. The updated DSI Studio allows for the use of multiple tractography atlases.
- 2023/10/02: The Otsu’s threshold was updated to ignore zeros values in the background, as a result, the equivalent value will be slightly different if there are zeros in the background. The seeding region in automatic fiber tracking was updated to provide more comprehensive mapping. The previous version seeds within a more restricted region designated by the atlas and some branches may not be fully covered. The updated version will have a much larger seeding region to get better coverage.
