In the prior system, the delay was 41 ms. This is true for all software control systems. See Adam Kerr for how to adjust Psychopy and E-prime to account for this delay.

			[http://www.psychopy.org/ Psychopy] is a nice open-source experiment control system. There is a GUI experiment builder (like e-prime), or you can write code using the Pschopy library calls (like Psych Toolbox). To trigger the scanner from Psychopy, add a [http://www.psychopy.org/builder/components/code.html code component] with this in the "begin experiment" section:

			import serial

			And add this to the "begin routine" section:

			device = '/dev/ttyACM0' # NOTE: replace this with your actual device!
			try:
			ser = serial.Serial(device, 115200, timeout=1)
			ser.write('[t]\n');
			ser.close()
			except:
			pass

			Note that you might need to change the "device=" line to reflect the actual location of your device. On linux, it will likely be /dev/ttyACM0. On OS-X, it will be something like '/dev/tty.usbmodem12345'. (See the [[MR_Hardware#USB-to-Serial_Port_Trigger\|MR Hardware page]] for more details.)
