Hello, dear software engineer
I want to do source localization the component of N2pc. At present, i have calculated N2pc in brainstorm, but i do not know how to compute sources.
N2pc is a difference wave of some paied electrodes.The posterior scalp electrode recording site on the opposite side of the searched target stimulation site produced a larger negative component of 200-300 ms than the ipsilateral recording site, called N2pc. The N2pc is defined as the difference between target's location contralateral and ipsilateral waveforms , which was made explicit by constructing a contralateral-minus ipsilateral difference wave.
I have calculated N2pc by construct two clusters, but it seems cannot compute sources of this component.Any help would be much appreciated!
