SSVEP File Writer
Component Type: Actuator (Subcategory: Brain Computer Interface)
This plugin writes to a text file the 4 EEG channels along with a software trigger received through the event listener ports. This file is lately analyzed by the ProtocolSSVEPTrain plugin to obtain the optimus frequencies to be used on the SSVEP detection.
