How to use

This program require only minimal knowledge of Matlab. The basic manipulations the user needs to do are the following: feed the cleaned EEG data into the pipeline, select a saving directory, select the analysis techniques he wish to undertake and then enter the required variables for each techniques.

  1. Cleaning of EEG data in eeglab: The cleaning of the EEG data need to be done in eeglab because the pipeline uses the EEG structure file made by exporting data from eeglab. For more information about eeglab follow this link. Clean the EEG data until it is ready to be analyzed and then proceed to step 2.
  2. Export data as a Matlab structure file: When your raw EEG has been cleaned enough to be analyzed go back to the main window in Matlab with eeglab still opened. In the workspace right click on the EEG structure file and select Save As…. Select where you want to save the EEG structure file, give the data a name and select save. You are now ready to analyze your EEG data.
  3. Set working directory: Before doing any kind of analysis you must first select where the data will be saved. To do so you need to press the “Set Working Directory” button and select in which directory you wish to save your data. The result of the different analysis techniques will be saved in a main folder that correspond to the name given to the EEG data in eeglab. Each EEG techniques will have its own folder inside the main folder.
  4. Load EEG data: Then you need to select which EEG structure files to work with during an analysis session. You will need to click on the “Load EEG Data” button and load the EEG structure file that was previously saved from egglab. You can select more than one EEG data set by holding ctrl while selecting you EEG structure files.
  5. Selecting Analysis techniques: Select and click on the radio-button next to the name of the analysis techniques you wish to perform on the loaded dataset. A window will open for each analysis technique that will prompt you to enter some variables related to the given analysis.
  6. Running the pipeline: When all the analysis techniques desired have been selected then you only need to click "Launch Analysis" and wait for the pipeline to be done calculating!
