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.
