Introduction
Lead-DBS is an open-source, MATLAB-based toolbox to localize and visualize electrodes in patients treated with deep brain stimulation. Importantly, the toolbox is intended for research and not for clinical use. First, this user guide focuses on Lead-DBS and single patient analysis with co-registration, normalization and reconstruction. Second, the user guide covers group analyses with Lead-Group.
This user guide is intended to cover most use cases. It pairs well with the primer for post-operative CT data or postoperative MR data. It also goes well with the basic walkthrough video and a more recent walkthrough video (Lead-DBS v2.5 new tools). For troubleshooting or other questions, the Lead-DBS community offers great support on the Slack user channel.
Quick history: Lead-DBS was initially developed at the Movement Disorders Unit of Andrea Kühn, Department of Neurology, Charité – University Medicine (CCM), Berlin, Germany. Since 2019, the Network Stimulation Laboratory of Andreas Horn has been coordinating the development.

Key Features
Linear and nonlinear registration of MRI and CT images
Reconstruction of the electrode trajectories
Manual correction of the electrode localization
Visualization of results in 2D slice views
Visualization of a 3D model showing DBS electrodes and their target areas

Group analysis
Dependencies
Lead-DBS is a collection of tools for the purpose of DBS electrode reconstructions and related processing. The core job of our development team is to find and integrate the best neuroimaging tools available within the open-source community and develop our own code where no good code can be found. Thus, Lead-DBS heavily depends on other tools that should be referenced properly if used for research projects. Please find a list of tools used by Lead-DBS here.
