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.
Please cite the reference paper when you have used FieldTrip in your study.

Mats presents âreproducescriptâ in JOSS podcast
Mats van Es was interviewed by Arfon Smith and Abby Cabunoc Mayes for the JOSSCast, a podcast about using open source to accelerate research. Mats explains how the reproducescript option can be used with all FieldTrip functions to generate a standardized and linear analysis script that is easy to share, as explained in our recent paper Reducing the efforts to create reproducible analysis code with FieldTrip. Furthermore, they discuss MATLAB and Python, and how to reduce barriers for sharing analysis code.

From about 2009 we used a locally hosted Bugzilla server as âissue trackerâ to maintain and distribute to-do lists and supports the follow-up communication between developers and users. Since about 2016 we moved on to GitHub for project management and issue tracking. We would occasionally still look up some old Bugzilla discussion regarding features, code design choices and bugs.
However, due to resource limitations and security concerns we decided to discontinue the Bugzilla server. As of now, https://bugzilla.fieldtriptoolbox.org contains a read-only archived copy of the bug reports and discussions. All links from the website and from the email archive to bugs on Bugzilla should still work, so the details of past work are not lost.
