Analysing data

There are several options for analysing MEG and EEG data from the Neuromag machine at the CBU:

FreewarePackages

These are the most intensively used freeware software packages for EEG/MEG analysis at the CBU:

[http://imaging.mrc-cbu.cam.ac.uk/meg/SpmAnalysis SPM]

[http://imaging.mrc-cbu.cam.ac.uk/meg/AnalyzingData/MNE_overview MNE]

[http://fieldtrip.fcdonders.nl/ Fieldtrip], [http://imaging.mrc-cbu.cam.ac.uk/imaging/FieldtripAnalysis Fieldtrip at CBU]

developed at the [http://www.fil.ion.ucl.ac.uk/spm/ FIL] and at the [http://imaging.mrc-cbu.cam.ac.uk/meg/SpmAnalysis CBU].

developed at [http://www.nmr.mgh.harvard.edu/martinos/userInfo/data/sofMNE.php MGH]

developed at the [http://www.ru.nl/neuroimaging/ Donders centre].

For some more details look [http://imaging.mrc-cbu.cam.ac.uk/meg/FreewarePackages here]. For an introduction and overview to different analysis approaches see our [http://imaging.mrc-cbu.cam.ac.uk/meg/MEGday29Jan10 "MEG day" presentations].

Other options are:

[http://nutmeg.berkeley.edu NUTMEG]

Matlab toolbox for EEG analysis (incl. ICA)

MEG/EEG analysis toolbox in conjunction with SPM8

CommercialPackages

We've got one or more licenses for the following software packages:

Neuromag Software

The [http://imaging.mrc-cbu.cam.ac.uk/meg/NeuromagSoftware Neuromag software] is part of the [http://www.elekta.com/healthcare_international_elekta_neuromag.php Elekta Neuromag MEG system] ([http://imaging.mrc-cbu.cam.ac.uk/meg/VectorviewDescription Vectorview configuration]). You can get a general idea about the analysis pathway from the [attachment:MEGAnalysisLectureJan07CBU.pdf CBU introductory lecture into MEG analysis] (the slides do not include the live software demos given at the lecture).

MaxFilter

[http://imaging.mrc-cbu.cam.ac.uk/meg/Maxfilter MaxFilter] is an essential pre-processing tool for MEG data, in order to remove noise sources likely to originate from outside the sensor array.

More info on pre-processing (e.g. trigger coding)

If all this is new to you...

...you should start on our [http://imaging.mrc-cbu.cam.ac.uk/meg/Beginners Beginners' Pages], with links to tutorials and more information on Matlab, Linux, Python etc.

Literature, Mailing Lists, Web-Sites and Events around MEG

Here you can find [http://imaging.mrc-cbu.cam.ac.uk/meg/MEGpapers a list of papers] and [http://imaging.mrc-cbu.cam.ac.uk/meg/MailingLists of mailing lists, web-sites and events] for various MEG-related topics.
