I have an EEG channel file with 256 channels. After imported in BST, I want to select specific 128 channels of EGI Geodesic Sensor Net systems. Is it possible to do this? I found that add EEG position have the GSN-128 option, but I don't know whether this is applying the default positions or selecting the specific 128 channels from my 256 channels file. Can you help me?
Please use the montage feature of Brainstorm to select the desired subset of channels.
