Below between the double lines is the script that I wrote: Btw, ksy is the subject's name and the number after it is the session number. tended infomax ICA using runica from the EEGLAB toolbox. ICA is a linear decomposition technique that aims to reveal the underlying statistical sources of mixed signals and is further a powerful tool to attenuate stereotypical artifacts (e. EEG Blink Removal Using APECS Introduction APECS is a collection of MATLAB m-files, based upon Dr. Note, this script should not just be run in one go, as there were steps that required manual additions (epoch rejection, specificatio of EOG related ICA components). Mathematically, x = As where:. But, this can give you a starting point for building a script that involves all stages of ERP data analysis. The final dataset includes a ground-truth ICA decomposition that can be used to verify the accuracy of newly calculated decompositions. The inputs and outputs of each tool will be compatible with those tools in the NEMO ERP Analysis Toolkit.
