To add a peak: right-click on the blue line in the top graph.
To delete a peak: right-click a peak (the following trough will be removed too).
Running from Matlab:
load D:\Working\WHH\all3101
% run_pd
x = D.recording{1}.ts.pleth.Time * 60;
y = squeeze( D.recording{1}.ts.pleth.Data );
O = peakdetect_gui( y, x );
