FieldTrip is a MATLAB software toolbox for magnetoencephalography (MEG) and electroencephalography (EEG) analysis.
The development of FieldTrip is supported by funding from the BrainGain, Human Connectome and ChildBrain projects.
The FieldTrip software is released as open source under the GNU General Public License.
The toolbox includes algorithms for simple and advanced analysis of MEG, EEG, and invasive electrophysiological data, such as time-frequency analysis, source reconstruction using dipoles, distributed sources, beamformers, and non-parametric statistical testing.
Though it contains some graphical user interface elements (mostly concerned with results visualization), it is mainly targeted towards batch-scripting of the formerly mentioned analysis protocols.
