[FieldTrip] Connectivity comparison across conditions

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

Hi Jose,

I can think of one out of 2 things:
-you formulate a null hypothesis pertaining to a group of subjects, and do statistical inference across subjects (e.g. by permuting the condition labels), or
-you formulate a null hypothesis pertaining to the observations belonging to the individual conditions, and do statistical inference across observations, e.g. by permuting the trial labels.

Best wishes,
Jan-Mathijs

Hi,

Is there a straightforward way to compare any connectivity measure at a given frequency (say, plv at 30Hz between electrodes 1 and 2) across conditions? I end up with one value per channel combination per frequency per condition, so what is the right way to compare?

Thanks in advance,

Jose Rebola
