FieldTrip

FieldTrip is a Matlab toolbox for MEG/EEG analysis that is being developed by the F.C. Donders Centre (FCDC) in Nijmegen, the Netherlands. The toolbox includes algorithms for simple and complex analysis of MEG and EEG data, such as time-frequency analysis, source reconstruction using dipoles, distributed sources and beamformers and non-parametric statistical testing. It supports the data formats of all major MEG systems (CTF, Neuromag, BTi) and of the most popular EEG systems, and new formats can be added easily. It contains high-level functions that you can use to construct your own analysis protocol in Matlab. Furthermore, it easily allows developers to incorporate low-level algorithms for new EEG/MEG analysis methods.
