[FieldTrip] Parcellate the reconstructed source time series

[Schoffelen, J.M. (Jan Mathijs)]

I want to parcellate the reconstructed source time series (~ 1000ms).
I have moments in source.avg.mom for around 6000 grids.
Additionally, do I need to perform some normalization on time series before or after parcellation to perform network analysis?

Well, at least you should compute a metric between pairs of time series that can be subjected to a network analysis. Whether or not this needs ‘some normalization’ depends on what you exactly want to achieve.

Best wishes,
Jan-Mathijs
