Fieldtrip is an MEG/EEG analysis software package developed at the Donders Institute. Fieldtrip has a number of options for time-frequency analysis and coherence analysis, and starting with SPM8 shares functions and data format with SPM.
Locally Fieldtrip is installed in:
The Fieldtrip developers release nightly snapshots of the code, so Fieldtrip "versions" are denoted by date. To use Fieldtrip, add one of these folders to your Matlab path, e.g.:
Like other changes to your Matlab path, you can save this to your path directly (File > Set Path) or add that line to ~/matlab/startup.m.
Fieldtrip will be updated when there are major changes to the code, or otherwise just to keep current with development (every 2 months or so). Old versions will be kept for at least one year.
The current version is always linked from /imaging/local/software/fieldtrip/fieldtrip-current.
Note that to add all of the required subfolders you may want to call fieldtripdefs in your script.
- No GUI, so some Matlab knowledge is required
- Analyses are generally highly customizable
- Shares data format with SPM8
- Strengths include time/frequency analysis, coherence measures, and nonparametric statistics
The best place to start is the series of excellent tutorials on the Fieldtrip website: http://fieldtrip.fcdonders.nl/getting_started and http://fieldtrip.fcdonders.nl/tutorial. A very brief local introduction can be found at FieldtripAnalysis.
