- EEG epoching is a procedure in which specific time-windows are extracted from the continuous EEG signal. These time windows are called “epochs”, and usually are time-locked with respect an event e.g. a visual stimulus.
- Furthermore, when executing EEGLab in a Script, there is often no need to keep a separate ALLEEG structure. extract a series of epochs by event types into different...
- Jul 20, 2016 · The rest is done by EEGLAB itself (like adding path etc.). Then just simply load your dataset and click compute FAA. Then your FAA index appears in command window. You have to use one epoch/event type dataset. So if you have several epoch types you have to extract one by one and save them first separately. Only then my toolbox works as you ...
