% ENTRY POINT FOR THE STREAMER GUI
% requires: eeglab with load_xdf plugin, LSL libraries for Matlab
%
% insert path and filename at the indicated positions 
% eeglab will load dataset and stream the eeg data alongside with the
% markers via an LSL stream

% STREAMCONTROL MATLAB code for streamControl.fig
%      STREAMCONTROL by itself, creates a new STREAMCONTROL or raises the
%      existing singleton*.
%                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
%      H = STREAMCONTROL returns the handle to a new STREAMCONTROL or the handle to
%      the existing singleton*.
%
%      STREAMCONTROL('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in STREAMCONTROL.M with the given input arguments.
%
%      STREAMCONTROL('Property','Value',...) creates a new STREAMCONTROL or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before streamControl_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to streamControl_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
