FieldTrip is the MATLAB software toolbox for MEG and EEG analysis that is being developed by a team of researchers at the Donders Institute for Brain, Cognition and Behaviour in Nijmegen, the Netherlands in close collaboration with collaborating institutes. The development of FieldTrip currently receives support from the ChildBrain project and from the Netherlands Organization for Scientific Research (NWO) and has previously been supported by the Human Connectome project and BrainGain.
The toolbox offers advanced analysis methods of MEG, EEG, and invasive electrophysiological 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, Elekta/Neuromag, 4D/BTi, Yokogawa) and of most popular EEG systems, and new formats can be added easily. FieldTrip contains high-level functions that you can use to construct your own analysis protocols in MATLAB. Furthermore, it easily allows developers to incorporate low-level algorithms for new EEG/MEG analysis methods.
This FieldTrip website is a Wiki (just like Wikipedia), which allows all visitors to contribute, very quickly and easily, without the need for registration.

We would like to invite you to contribute to Frontiers in Neuroscience Special Research Topic “From raw MEG/EEG to publication: how to perform MEG/EEG group analysis with free academic software”. The idea is to create a collection of well-described group analyses of EEG and MEG data that can be fully reproduced by anyone and ported by researchers to their own data. Furthermore, as the analyses will be endorsed by peer review, any analysis choices will be citeable in future publications. This will hopefully contribute to wider adoption of good practices by the MEG/EEG research community.

We are presenting the “MEG group analysis” satellite symposium at Biomag 2016 in Seoul. This is a joint effort of the FieldTrip, MNE, BrainStorm, Nutmeg and SPM teams. The presentations and especially the (annotated) analysis scripts are all shared here.

We are looking for ways to further extend the FieldTrip training. The team in Nijmegen is small, and cannot be traveling all the time. If you are interested in organizing your own workshop, let us know. We will share our workshop material and slides with you!
Diego just completed a FieldTrip workshop in Guangzhou with a focus on ECoG analysis. You can see more photo's on our Facebook page.

Last week we hosted the MEG/EEG toolkit course in Nijmegen with 60 participants from all over the world. We had 4 days of lectures, hands-on sessions and good discussions on MEG/EEG data analysis. Some photo's that give an impression of the event are on our Facebook page.

The FieldTrip development has completely moved over to github. This makes it much simpler for us to incorporate external suggestions and for you to directly contribute to the code. We have a tutorial that explains how you can use git and github.

Andre and Jan-Mathijs have just published a tutorial review of functional connectivity methods and their interpretational pitfalls. Along with the paper comes a set of FieldTrip scripts that allows you to simulate and investigate issues that are discussed in the paper. Go and check it out!

Wow, we just got the 1000-th citation to our FieldTrip reference paper!
