function snirf = demo_snirf_readfile(fname)

% Syntax: 

%    demo_snirf_readfile()

% Description:

%    Demo of how to read individual SNIRF fields using SnirfClass methods.

%  

% Examples:

%    demo_snirf_readfile();

%    demo_snirf_readfile('Simple_Probe.snirf');

%    demo_snirf_readfile('FingerTapping_run3_tdmlproc.snirf');

%    demo_snirf_readfile('neuro_run01.snirf');

%    snirf = demo_snirf_readfile();

%    snirf = demo_snirf_readfile('Simple_Probe.snirf');

%    snirf = demo_snirf_readfile('FingerTapping_run3_tdmlproc.snirf');

%    snirf = demo_snirf_readfile('neuro_run01.snirf');
