MEG Freeware Packages

There are many available; here are some (some comments may reflect ignorance!)

SPM5

Advantages:

Much experience at CBU, integrated with fMRI analysis
Matlab, so readable and extendable
Advanced statistical methods (e.g, for multiple comparisons across space or time),
Novel variants of the L2-norm approach to the inverse problem
Group-based analysis (eg in MNI/Talairach space).

Disadvantages:

Currently installed on all Linux Boxes (lowest load box selected by spm 5 eeg at linux prompt)

For more details, see here SpmAnalysis

Advantages:

Advanced distributed solution methods (by Matti Hämäläinen, a long-standing expert with strong links to Neuromag)
Excellent, fast graphics
Linked with Free Surfer http://imaging.mrc-cbu.cam.ac.uk/imaging/FreesurferInformation (advanced software for MRI segmentation, extraction of cortical surfaces, and inflation/normalisation)
Matlab Toolbox, for exporting and importing data

Disadvantages:

Compiled code, so difficult to extend (though it does come with an extensive MATLAB toolbox, which is arguably the best way to read FIF data).

Installed on Linux Boxes. All Graphical tools must be used in the computing room on lws001, lws002, lws004, lws005, lws006 or using a vncserver.glx session (see http://imaging.mrc-cbu.cam.ac.uk/imaging/ImagingComputingDevelopments).

For more details, see here MneAnalysis

Matlab tools for applying multiple linear regression to EEG/MEG data. More here: LinearRegression You may want to follow the following AnalysisPath

Advantages:

Strong in oscillatory analysis (time-frequency, coherence) and beamformers (eg DICS)
In Matlab, so easily readable and extendable

Matlab utilities for quality control of your data prior to further processing. More here: DataScreeiningTool

FIFFACCESS for simply reading FIF data into Matlab, more here: ReadingDataInMatlab
EEGLAB (good for ICA) http://www.sccn.ucsd.edu/eeglab/
Brainstorm (good for forward models) http://neuroimage.usc.edu/brainstorm/
