FieldTrip is the Matlab software toolbox for MEG and EEG analysis that is being developed at the Centre for Cognitive Neuroimaging of the Donders Institute for Brain, Cognition and Behaviour 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 software 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.

Stephen Whitmarsh and Saskia Haegens just returned from the FieldTrip workshop at the City University of New York. The workshop was received with great enthusiasm and we already started thinking about a follow up workshop in New York. There are some photos on our FaceBook page.

The maillist service at SurfNET is being terminated as of 1st of January 2011. Therefore the list has now moved to a different location and a different organisation. The Science Department of the Radboud University has kindly provided us with new maillists, to which I have subscribed all existing subscribers, EXCEPT those who were somehow invisible, so please check if you received this e-mail, but not something from fieldtrip@donders.ru.nl

All changes to the code can be tracked on Twitter or Google Code.

• Revision 5183: enhancement - added test script for bug 1254 (compiled qsubcellfun)
• Revision 5182: bugfix - solved a problem with stacking, which caused the example mentioned in t
• Revision 5181: making (two) testscripts compatible with new test data folder structure
• Revision 5180: moving fetch_vol and fetch_sens to private folder
• Revision 5179: added join_str private function to replace various subfunctions doing the same t
