% tstool is a matlab toolbox for nonlinear time series analysis
% which includes a graphical user interface (GUI) 
% 
% The command 'tstool' creates a GUI that allows
% the user to perform data manipulation and analysis
% with a wide range of classical and modern nonlinear methods
%
% An optional input argument may be given : The directory path
% from which tstool will load signal files
