fitConnectivity estimates the functional connectivity between activated regions in an ARF model based on trial-to-trial amplitude variation.
It uses the single-trial data (extracted from the raw time-series using makeSingleTrialEvents
), to estimate the trial-by-trial amplitudes of
each region in the ARF model.

An ARF model object (class |
funcfilename |
Filename of the volume containing the single-trial data. |
Each volume of the file specified in funcfilename should contain estimates of a single-trial (see makeSingleTrialEvents
).
Returns an object of class arfcorrelation
including the region by time matrix of amplitude time-series and the estimated correlations.
