Welcome to the FieldTrip homepage

FieldTrip is a 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 project. 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 and EEG 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.

This FieldTrip website is a Wiki (just like Wikipedia), which allows anyone visiting the site to add, remove, or otherwise edit all content, very quickly and easily, without the need for registration. The IP addresses of people that make changes are logged, and they can be blocked if needed. Please act responsibly and only make changes that improve this site.

The wiki system has just been upgraded to the latest version (dokuwiki-2009-12-25c).

16 December 2009

… we have decided to start adopting the same naming scheme that SPM is using. That naming scheme consists of prefixing the function name with the name of the toolbox, e.g. spm_contrasts. The prefix that FieldTrip will use is “ft_”. So that means that the FieldTrip preprocessing function will be renamed into ft_preprocessing, sourceanalysis will become ft_sourceanalysis, freqanalysis will become ft_freqanalysis, etc. This will affect all publicly available FieldTrip functions, i.e. the main functions that you are using…

Recent changes to the code

  • ft_mvaranalysis.m: ensure the presence of a trl in data.cfg which is fieldtrip consistent

2010-03-10 10:22 roboos

  • peer/peercellfun.m: added timcv for user-specified coefficient of variation, affects the resubmission timeout

2010-03-10 09:50 roboos

  • realtime/rt_fmriviewer.m, realtime/siemens/matlab: moved siemens/matlab/fmri_viewer to realtime directory

renamed it to rt_fmriviewer

  added cfg.bufferdata so that you can start viewing at the first sample instead of the last

  • compat/stats, compat/stats/tcdf.m, compat/stats/tinv.m: created subdirectory to contain the drop in replacements from the mathworks stats-toolbox
