 The scanner trigger pulse is the most important external input signal you need to think about when running two programs, because that is the best way to make sure they are accurately synchronized with each other (and with the scanner). BIAC provides the scanner trigger signal on multiple different input devices, which means that two programs can read the same trigger signal, provided they read it on different hardware channels. CIGAL should be configured, therefore, to read the scanner trigger from the analog input device, which it has open anyway in order to record the physiological waveforms. That allows the other program to access the scanner trigger pulse from the serial response box (EPrime SRbox), or from a parallel port input (probably no longer available on Windows 7 computers), or by simply manually starting the program by pressing a keyboard key. Since CIGAL will trigger from the scanner automatically, you are free to start your other program however you like, provided it does not use the Measurement Computing USB analog/digital device. The scanner trigger pulse is the most important external input signal you need to think about when running two programs, because that is the best way to make sure they are accurately synchronized with each other (and with the scanner).
