I am just setting up a new Active Two system. Could anyone help me with a model experiment (no matter how simple it is or what it is) for either e-prime or presentation? I do not know how to send signals from the stimulus presenation computer (the cable is connected) to the EEG acquisition computer, a model could help me a lot.
thank you if anyone could help!

model experiment
Hi Emese,
I have performed a tipical oddball paradigm where just two types of auditory stimulus are used. To send different code infomation to the active system view I would write to the presentation editor:
sound sound1; # name of your sound
time= XXXX;
code= "s1"; # codification that will be used for the presentation report at the end of the experiment
port_code=1; #type of trigger that will be registered by labview.
sound sound2
time=XXXX;
code ="s2";
port_code=2; #As you see, diferent stimulus is typed in another trigger code. Triggers are signaled by a red square at the bottom of the labview screen.
Further, previously playing your scenario, you should enabling trigger transmission information by adding one port output to the "port settings" configuration.
I hope it could help you,
Lluís.
