4 Functions and variables

4.1 Functions

The following list of functions is available. Each of these functions resides in the BioNES.m files (See brief description in Table 3.1). Additionally, the BioNES.m file includes different callback functions associated with different sub-components of the GUI. These are self-explanatory with a brief explanation given in the function file itself.

SYNTAX	DESCRIPTION
`BioNES(varargin)`	Main function.
`Help(varargin)`	Holds the callback functions of the help GUI.
`CalculateResults(handles)`	Calculates the final results like recorded session duration, sampling frequency, number of samples, and data quality.
`connectArduino(handles,string)`	Defines the logic to connect with the `Arduino` board.
`connectGame(handles)`	Connect with the `FCEUX` and start the game.
`GuiStates(handles, string)`	Initialize the GUI sub-components as per various states.
`InitializeVariables(handles)`	Function file that initializes variable to their default state.
`logSys(handles, logString)`	Log system state for debugging.
`SetParam(handleName, string, color, handleType)`	Set color and text parameters for various GUI components.
