[FieldTrip] Visualization of Channels for Human Connectome Project MEG data

[Tolga Ozkurt]

Dear Fieldtrip list,



I was seeing the MEG files uploaded by “Human Connectome Project”, which
seem to be pre-processed by Fieldtrip. The resting data were collected in
supine position with 4D Neuromag 248 channels.



When I use the standard command for layout



cfg.layout       = '4D248.lay';



the channel locations do not seem to fit. (Please see the attached figure).
I do not quite know the channel distribution of the system; but it seems
some channels are out of the head.



Could you give me an idea to project the channel layout properly?



Thank you.



Tolga
