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.

Our technical group has to do some maintenance to the servers of the Donders Centre. The consequence is that the fieldtrip wiki (http://fieldtrip.fcdonders.nl) and the ftp server (ftp.fcdonders.nl) will be down. Hopefully the downtime will be only one evening, but it might extend into the next morning. See below for details.

Tomorrow Wednesday June 23rd, 18:00h CET we have planned a down-time window for central storage and all of the central storage dependent IT services! If everything goes smoothly, central storage and all services will be back up and running later in that evening. In case we encounter unforeseen problems down-time might last until the early next morning Thursday June 24th.

The BIOMAG conference in Dubrovnik has just ended. During the conference there was great interest in applying FieldTrip to MEG data of all sorts. Furthermore, there is a clear commitment of developers of new methods and of other software toolboxes to further strengthen the collaboration and sharing code and expertise.

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

… 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…

  • ft_freqanalysis.m: fixed bug with dof calculation mtmconvol

2010-07-29 12:48 crimic

  • ft_databrowser.m: modified to fit with new data.sampleinfo field, For datasets without such a field it defines one on the fly recovering information from other data fields
