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.

We are coming up to the 100-year anniversary of the discovery of human EEG.
In celebration of this seminal moment for human neuroscience, we are asking the FieldTrip, the EEG, and the neuroscience community at large, to document the impact this discovery has had on our understanding of the brain and to share thoughts on the short, medium, and long-term future of human non-invasive scalp EEG through this online survey. Importantly, this survey will also help in defining our collective perspectives on future research priorities.
I hope you will be able to spare the 10-15 minutes it will take to complete the survey and make your views heard about the past and future of EEG.
Thank you for your time.

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.

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 âonâ! 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 ânetwork file systemâ and treat it as a network drive.
