[FieldTrip] ICA components for gradiometer sensors

[Lin Wang]

Dear all,

I applied ICA ('runica' method) to 202 gradiometer sensors (collected with
neuromag system) after removing two bad channels and some trials that
contained obvious artifacts. I could identify the EOG and ECG components,
but the topographic distributions of the components look quite weird to me
(i.e., the strips).

I attached a screenshot of some components in the email. Could you help me
to see whether there is anything wrong with the ICA analysis?

Thanks a lot!

Best,
Lin
