[FieldTrip] source-level cluster analysis?

Hi all,

I am analyzing an MEG dataset in which I only have access to source-level data. I ran cluster-based permutation tests on the data with pre-defined ROI-s but I was wondering if it would make sense not to pre-define ROI-s but search for spatial clusters with a cluster-based permutation test. I’m not familiar enough with MEG, so I can’t decide if the features of source-level data would allow me to run the cluster analysis the same way described here for sensor-level data: https://www.fieldtriptoolbox.org/tutorial/cluster_permutation_freq/.

Would cluster-based permutation test work as well with source-level data as with sensor-level data? If so, what kind of layout file should I use? Positions of sensors/electrodes can be defined with two coordinates but sources can be only defined with three coordinates.

Thanks so much in advance for any advice!

Best,

Eniko
