SimNIBS 2.0 is a free software package for the Simulation of Non-invasive Brain Stimulation. It allows for realistic calculations of the electric field induced by transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS).
SimNIBS 2.0 consists of two main parts:
A command line script is used for the automatic generation of tetrahedral volume meshes of the head from MR images.
These volume meshes are then used in the electric field calculations based on finite elements. A graphical user interface (GUI) is provided to set up the calculations.
The Installation section describes how to download and set up SimNIBS under Ubuntu and Mac OS X.
The Documentation section guides you through SimNIBS in a step-by-step fashion based on an example data set.
Note: SimNIBS is a research tool. Clinical usage is not supported or advised. In particular, SimNIBS was not tested to give accurate results in the presence of pathological condition
The documentation for SimNIBS 1.0 can still be found here. We do not recommend using version 1.0 any longer, but the documenation is kept in case you have ongoing projects based on it.
