** Code Documentation ** 

   * RunSpectralEvents_IndividualChannels.m
     * Set desired task (Resting_State, MGS, SNR)
     * Set epoch (Delay or Fix; only is running resting state)
     * Set seconds; only if running delay epoch
     * Set band to analyze (gamma, beta, theta, alpha)
     * Pull subjects from the preprocessed folder 
     * Calls createXmatrix_individualChannels.m that organizes the data in the correct format that the spectral event code expects
     * Creates an array of values corresponding to the trigger values, called classLabels
     * Defines event band and frequency values based on which band you're running
     * Runs the spectral event toolbox, see [[https://github.com/jonescompneurolab/SpectralEvents|Spectral Event Toolbox]]
     * Saves out large structs of the subjects spectral event data

   * SpectralEvents_Struct_Extraction.m
     * Initialize task, epoch, and band
     * Load in the structs
     * Extracts out the Event Number, Power, Duration, Max Power, and Max Frequency and generates the average of each
     * Crates a large table with all the subjects data

  * Run SpectralEvents_Analysis.R
    * Assesses all the age relations with the spectral event measures and associations with behavioral measures
