Welcome to the FieldTrip website
FieldTrip is the MATLAB software toolbox for MEG, EEG and iEEG analysis, which is released free of charge as open source software under the GNU general public license. FieldTrip is developed by members and collaborators of the Donders Institute for Brain, Cognition and Behaviour at Radboud University, Nijmegen, the Netherlands.

From May 22-26 we will host our annual MEG/EEG toolkit course at the Donders in Nijmegen. In this 5-day course we will teach you advanced MEG and EEG data analysis skills. Pre-processing, frequency analysis, source reconstruction, connectivity analysis and various statistical methods will be covered. The toolkit consists of a number of lectures, followed by hands-on sessions in which you will be tutored through the analysis of a MEG data set using the FieldTrip toolbox. Furthermore, you have the opportunity to work on your own data with the guidance of experienced tutors.
Preregistration is now open, see here.

With the negative developments of Twitter, we feel it is more appropriate to continue posting news item and release updates on Mastondon. you can continue to follow us on https://fosstodon.org/@fieldtriptoolbox.

A while ago we have added some new visualization functionality to ft_multiplotER, which now allows for MNE-Python style butterfly plots, such as in the attached image. All you need is to specify some options in your cfg:
cfg.viewmode = 'butterfly',
cfg.linecolor = 'spatial', along with the proper layout. Go and check it out!

After having been postponed for 2 years, Biomag 2020 is ‘on’! We are enjoying lively social interactions and discussions with our friends and colleagues, and listening to interesting scientific stuff. The picture shows our own Bob Bramson in action on the stage of the Bramall concert hall at Birmingham University.

In a few days, and after an absence of 2 years, we will again host our Donders advanced MEG/EEG-toolkit on-site. We are excited to finally be able to teach in real life again. With the help of our youngest future colleague all workshop PCs have been prepared and tested.

In the past we used an FTP server to distribute files, but as of April 2022 we switched to a new download server that can be found on https://download.fieldtriptoolbox.org. It supports WebDAV, which means that you can download individual files using your web browser. You can also download a complete directory (with subdirectories) at once using a specialized WebDAV client such as CyberDuck or FileZilla. On Windows and macOS you can even mount the WebDAV server as a “network file system” and treat it as a network drive.

From May 9-13 we will host the MEG/EEG FieldTrip data analysis toolkit at the Donders Centre for Cognitive Neuroimaging (DCCN) in Nijmegen. The toolkit course is aimed at PhD and postdoctoral researchers that already have some experience with EEG and/or MEG data acquisition (either a pilot or a full study) and that have a good understanding of their own experimental design. Furthermore, we expect that you know the basics of MATLAB and that you already have some experience with MEG/EEG preprocessing and analysis. We will teach you advanced data analysis methods and cover preprocessing, frequency analysis, source reconstruction, connectivity and various statistical methods. Furthermore, we will give attention to good practices for reproducible research, Open Data and Open Science.
We hope and expect that we will be able to teach this toolkit on site.
See the toolkit2022 page for further details.
