Performance of 2D-TCA in detecting spikes in patient runs when different cluster size thresholds are applied. Runs are sorted by EEG-fMRI activation size from highest to lowest.

Epileptic Activity Characteristics (obtained from EEG-fMRI data)				2D-TCA Results
Patient #	# of spikes	HRF Amplitude (% above baseline)	Size (voxels)	# of components	# of t-maps with activity	# of t-maps with cluster size of:
