Welcome to the FieldTrip website
FieldTrip is the MATLAB software toolbox for MEG, EEG, iEEG and NIRS analysis. It offers preprocessing and advanced analysis methods, 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 and of the most popular EEG, iEEG and NIRS systems. New data formats can be added easily. FieldTrip contains high-level functions that you can use to construct your own analysis protocols as a MATLAB script.
Please cite the FieldTrip reference paper when you have used FieldTrip in your study.

Two weeks ago, our external contributors Lau Møller Andersen (NatMEG, Stockholm) and Britta Westner (CFIN, Aarhus) presented a well-received EEG training workshop at the RITMO center at the University of Oslo. More information, including the material that they presented at the workshop can be found here. Are you also interested in organizing a workshop by yourself? Then check out this FAQ.

EEG-BIDS, an extension to the brain imaging data structure for electroencephalography and iEEG-BIDS, extending the Brain Imaging Data Structure specification to human intracranial electrophysiology have just been published in Scientific Data. These two papers describe the extension to the BIDS standard to allow it not only to store raw (f)MRI and MEG, but also EEG and iEEG data. The full specification is here; you can find further documentation and examples to work with BIDS here on this website.

Jan-Mathijs and Robert just published a paper in Scientific data, which is a Data Descriptor of our MOUS dataset, a 204-subject multimodal neuroimaging dataset collected by MPI and DCCN researchers, which is now shared with the wider research community at our Donders data repository. The data are organized according to BIDS. Go and check it out!

We just completed the first ECoG/SEEG toolkit at the UC Davis Medical Center in Sacramento, California. The three-day event was packed with lectures, hands-on sessions, and fruitful discussions, with people visiting from all over the US (and beyond). Many thanks also to neurosurgeon Fady Girgis and neuroscientist Bob Knight for providing lectures on the clinical aspects and research applications of intracranial EEG. We plan to upload videos of the lectures, so stay tuned.

Check it out! Matthias Treder has kindly contributed a tutorial and some code (streamlined a bit by yours truly) that now allows you to perform MVPA analysis in FieldTrip, using his awesome MVPA-light toolbox ! For now it is well supported, documented and tested for channel level time domain data, but in the near future (and with your help) we will also ensure support for frequency domain and source level data. For now you can just use ft_timelockstatistics with cfg.method=’mvpa’. The tutorial can be found here.

All the best wishes for the new year to all of you on behalf of the FieldTrip team! According to Google Scholar, the FieldTrip paper has now been cited more than 3000 times. We are happy that the project provides so many of you with helpful tools that facilitate you to contribute to the scientific community.
