The development of FieldTrip is currently supported by funding from the BrainGain and the Human Connectome projects. The FieldTrip software is released as open source under the GNU general public license. text/html 2012-02-03T13:29:21+01:00 robert http://fieldtrip.fcdonders.nl/menu?rev=1328272161&do=diff * Home * Getting started * User documentation * Tutorial documentation * Walkthrough * Frequently asked questions * Reference documentation * Example matlab scripts * Development * How to contribute * Modules * Projects * Dashboard * Realtime BCI text/html 2012-02-02T12:03:36+01:00 http://fieldtrip.fcdonders.nl/development/specest?rev=1328180616&do=diff The spectral estimation toolbox for FieldTrip, the specest module, contains a consistent set of functions for spectral estimation and decomposition of electrophysiological data. These specest functions allow other projects (such as SPM) to re-use the implemented methods separate from FieldTrip and facilitates external contributions to FieldTrip by separating the user interface from the functionality. text/html 2012-02-02T11:21:32+01:00 http://fieldtrip.fcdonders.nl/development/modules?rev=1328178092&do=diff There are some low-level features of the FieldTrip code that are of interest to other Open Source software developers. To facilitate the re-use of those functions, we have split them off into seperate modules. You can download these modules as stand-alone code from our ftp server, and use them in your own projects. It would be nice if you attribute this to our work, e.g. by providing a link to our FieldTrip website. text/html 2012-02-01T16:08:43+01:00 lilla http://fieldtrip.fcdonders.nl/tutorial/minimumnormestimate?rev=1328108923&do=diff tutorial, timelock, source, meg, headmodel, mri, plot Introduction In this tutorial you can find information about how to do source-analysis with minimum-norm estimate on the event-related fields (MEG) of a single subject. We will working on the dataset described in the preprocessing tutorials (Trigger-based trial selection, Event related averaging and planar gradient), and we will use also the anatomical images that belong to the same subject.

The Neuromag and Yokogawa MEG systems use two different kind of sensors, gradiometers and magnetometers. Gradiometer consists of two coils, and the data recorded of such a pair reflects the gradient of the magnetic field, measured in Tesla per distance unit. In contrast, magnetometers measure the magnetic field using one coil only, resulting in a measure in Tesla. Since the two type of sensors measure in different units, data o… text/html 2012-02-01T14:20:34+01:00 http://fieldtrip.fcdonders.nl/faq?rev=1328102434&do=diff faq On this page you can find (and add) answers to a variety of Fieldtrip-related questions. We invite you to add your own example scripts or frequently asked questions on the wiki. Also tutorials can be added. Every time you explain somebody something about Fieldtrip, please consider whether you could use the wiki for this so others can learn from it as well. text/html 2012-01-31T20:36:59+01:00 boris http://fieldtrip.fcdonders.nl/development/realtime/scratchpad?rev=1328038619&do=diff This page contains random remarks. For information on the FieldTrip realtime buffer, please refer to the buffer overview. closing the loop pipeline contains example fMRI pipeline description, as does the Siemens fMRI page. Various notes and commments Portability note: non-unix systems may not allow read()/write() on sockets, but recv()/send() are usually ok. This is true on Windows and OS/2, for example. text/html 2012-01-31T09:29:50+01:00 robert http://fieldtrip.fcdonders.nl/discussion_list?rev=1327998590&do=diff There is a FIELDTRIP email discussion list. The aim of the list is to facilitate the discussion between both users and developers of the FieldTrip toolbox, to share experiences and to discuss new ideas for MEG and EEG analysis. New releases and updates will also be announced through that list.

To inform the user about the requirements of each function call and thereby give him/her a better feeling on how to optimize the analysis using distributed computing, each FieldTrip function estimates the time and memory(*) it requires. This information about the call is printed at the end of the function, like this
