Welcome to OSS-DBSv2

OSS-DBSv2 is an open-source simulation toolbox for deep brain stimulation (DBS). It is designed for researchers and developers who want to model electric fields, stimulation volumes, and pathway activation in patient-specific or experimental setups.

The software can be used in two main ways:

  • through Lead-DBS for a GUI-driven clinical and research workflow

  • as a standalone Python and command-line toolbox for custom simulations, scripting, parameter sweeps, and method development

For most new users, the simplest path is to start with the standalone tutorial or, if you already work in Lead-DBS, with the Lead-DBS integration page.

What OSS-DBSv2 can be used for

OSS-DBSv2 supports several common DBS modeling tasks:

  • building model geometries from a simplified brain region or imaging data

  • placing predefined or custom electrode models in the simulation domain

  • assigning dielectric properties to tissue compartments

  • solving the volume conductor problem in isotropic or anisotropic media

  • evaluating fields on lattices, voxel grids, or pathway trajectories

  • integrating with Lead-DBS for stimulation volume and pathway activation studies

Typical inputs

A simulation is typically defined by:

  • a JSON input file describing geometry, electrodes, solver settings, and outputs

  • segmented MRI data, optionally combined with DTI data

  • a stimulation configuration with active contacts and signal settings

  • an output directory for logs, meshes, and simulation results

Typical outputs

Depending on the workflow, OSS-DBSv2 can produce:

  • electric field and potential solutions

  • impedance estimates

  • exported electrode and field data for visualization

  • lattice- or pathway-based post-processing results

  • log files and status files for reproducible batch runs

Where to start

If you are new to the project, the recommended path is:

  1. Installation

  2. Tutorial

  3. Input and Settings Reference

  4. Examples

If you want to drive OSS-DBSv2 from Python scripts instead of the CLI, see Python scripting API.

If you already use Lead-DBS, go directly to Using OSS-DBSv2 with Lead-DBS.

Documentation structure

The documentation is split into a user-oriented guide and a set of subsystem reference pages. Start with the user guide if your goal is to run simulations. Use the reference pages when you want more detail about geometry, materials, signals, point analysis, or the solver stack.

For more details about the first version of OSS-DBS, see [Butenko2019].
