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.

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.
