FieldTrip is the Matlab software toolbox for MEG and EEG analysis that is being developed at the Donders Institute for Brain, Cognition and Behaviour at the Radboud University Nijmegen, the Netherlands together with collaborating institutes. The development of FieldTrip is currently supported by funding from the BrainGain and the Human Connectome 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 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. 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.

We just completed the workshop in Toronto hosted by Thilo Womelsdorf. Martin Vinck (UvA) and Robert presented the spike and LFP data processing capabilities to a group of approximately 50 participants from various labs in Canada.

Some spammers have started targeting the FieldTrip wiki,trying to add URLs pointing to malicious content elsewhere. I have temporarily disabled the registration of new accounts. Please keep your eyes open for wiki pages that have been messed up, and use the “show previous revisions” → “edit” option to revert pages that have been damaged.
22-24 October, 2012
Roemer van der Meij and Robert Oostenveld just returned from the Center for Mind/Brain Studies (CiMeC) in Trento (Italy), or more precisely in Rovereto where most of the institute is, and in Mattarello, where the MEG lab is located. Upon invitation by Nathan Weisz and Angelika Lingnau we presented a workshop for the MEG group. We not only enjoyed the scientific interaction, but also the Italian ice cream and the beautiful scenery.
26-28 June, 2012
Johanna Zumer and Irina Simanova presented the FieldTrip toolkit in Krakow, Poland at Jagiellonska University, Departments of Psychology and Applied Psychology. The ERP hands-on was modified to focus on EEG data instead of MEG, and this Reading and pre-processing EEG data example page was created. Time-frequency analysis, beamforming, and multivariate analysis were also presented. Photos coming soon here and also on the FieldTrip facebook page.
