The peak detection can be run without the GUI. The x, y and flags are passed, and Pout returned.

Pout = peakdetect_run( y, x, flags );
x: time values
y: waveform

flags: parameters

flags.use_defaults: (optional) true uses default settings, false does not. 
flags.use_previous: (optional) true uses last GUI settings, false does not.
flags.timeunits: the time units of "x", used for calculating rate in Hz and cycles/minute (as in beats/minute, or breaths/minute)
flags.[parameter]: (optional) use specified parameter values, and default settings for other parameters.
