On the record
- Authoring tools
- Yessimdrift.readthedocs.io · read 24 Sep 2026
- Availability
- The project README describes simDRIFT as open-source software.github.com · read 11 Oct 2026
- Cell limits
- The reference recommends keeping total cell volume fraction at or below 0.40 because higher densities make sphere packing difficult and increase runtime.simdrift.readthedocs.io · read 11 Oct 2026
- Colab
- The quickstart provides GPU-enabled Google Colab installation steps for running an example simulation.simdrift.readthedocs.io · read 11 Oct 2026
- Colab workflow
- The quickstart describes a Google Colab GPU workflow for installing simDRIFT and running a basic simulation.simdrift.readthedocs.io · read 11 Oct 2026
- Configurable fibers
- Fiber bundles support user-defined radii, intrinsic diffusivities, orientations, and densities; the reference recommends no more than three or four bundles.simdrift.readthedocs.io · read 11 Oct 2026
- Data export
- Yessimdrift.readthedocs.io · read 24 Sep 2026
- Delivery mode
- desktopsimdrift.readthedocs.io · read 24 Sep 2026
- Diffusion schemes
- The reference lists built-in DBSI, ABCD, and NODDI diffusion schemes, and allows user-supplied b-value and gradient-direction files.simdrift.readthedocs.io · read 11 Oct 2026
- GPU requirement
- simDRIFT requires a CUDA device with compute capability 3 or higher and is compatible with Python 3.8 or later.simdrift.readthedocs.io · read 11 Oct 2026
- Implementation
- The GitHub project says simDRIFT is written in Python and uses Numba's CUDA API to simulate spin trajectories in parallel on GPU threads.github.com · read 11 Oct 2026
- Installation
- The guide recommends a dedicated conda environment and installs the package from its GitHub source repository using pip.simdrift.readthedocs.io · read 11 Oct 2026
- Intended users
- The documentation identifies diffusion MRI researchers as the intended users and says the software may also be useful for signal-processing or diffusion-imaging instructors.simdrift.readthedocs.io · read 11 Oct 2026
- License
- The GitHub repository identifies the project license as BSD-3-Clause.github.com · read 11 Oct 2026
- Mesh-free simulation
- The package describes its Monte Carlo simulations as mesh-free, avoiding the need to create meshes for tissue geometries.simdrift.readthedocs.io · read 11 Oct 2026
- Modeling limitation
- The simulation documentation says its cell random-walk implementation assumes zero exchange between compartments and is physically accurate only when diffusion time is less than the stated exchange time.simdrift.readthedocs.io · read 11 Oct 2026
- Model limits
- The reference recommends no more than three or four fiber bundles and says cell fractions above 0.40 can substantially increase runtime.simdrift.readthedocs.io · read 11 Oct 2026
- Outputs
- Simulation results can include spin trajectories, NIfTI signal files, an execution log, and a copy of the input configuration.simdrift.readthedocs.io · read 11 Oct 2026
