= Analysing data =

There are several options for analysis of MEG data from our machine available at the CBU:

 * NeuromagSoftware that comes with the machine (instructions on AccessingNeuromagSoftware at CBU)
 * CommercialPackages (CURRY, BESA, ASA, EMSE), for which we have licences (look here for a possible [http://imaging.mrc-cbu.cam.ac.uk/meg/AnalysisPath analysis route])
 * FreewarePackages, such as Fieldtrip, [http://imaging.mrc-cbu.cam.ac.uk/meg/DansPage MNE], and [http://imaging.mrc-cbu.cam.ac.uk/meg/SpmAnalysis SPM].

You can get some general feeling 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).

Whatever your analysis path is, you will most likely start by applying [:Maxfilter:Max Filter] on your raw data.

== If all this is new to you... ==

You may want to start with a basic [http://www.mrc-cbu.cam.ac.uk/research/eeg/eeg_intro.html introduction to EEG and MEG analysis].

Your life as a neuroimager will be much easier if you have a good grasp on Linux and Matlab. 

Matlab:

You can look at [http://www.mathworks.com/academia/student_center/tutorials/launchpad.html tutorials and demos] offered by Matlab itself. This site also contains links to Matlab tutorials at some universities. You may want to start with the [http://www.mathworks.com/access/helpdesk/help/pdf_doc/matlab/getstart.pdf Getting Started] section. 
The short introduction to [http://imaging.mrc-cbu.cam.ac.uk/imaging/LearningMatlab Matlab for psychologists] from the University of York is also useful.
