Description
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.
Usage
1
fitConnectivity(arfmodel, funcfilename="single_events.nii.gz")
Arguments
arfmodel
An ARF model object (class model)
funcfilename
Filename of the volume containing the single-trial data.
Details
Each volume of the file specified in funcfilename should contain estimates of a single-trial (see makeSingleTrialEvents).
Value
Returns an object of class arfcorrelation including the region by time matrix of amplitude time-series and the estimated correlations.
