The physioShow GUI is used to load and display the physiologic timecourses and average functional timecourse. First the Load button must be pressed to popup the physioLoad GUI for loading of the physiologic data. The PlotType menu allows the user to specify plotting of cardio, respir, average functional time series or all three of them. When spectrum check box is selected, the corresponding spectrum is also plotted. Note that the spectrum of the time series average is the "average of the time series' spectrums" and NOT the "spectrum of the average time series". For reference, a vertical line is plotted at the frequency specified in the field lineFreq.
