DLL File

This tasks uses parallel port to send event codes to an an acquisition device like BIOPAC. However, the package needs to verify the location of where this DLL file is located.

If you don't have a parallel port, ignore this step

1. Enable parallel port by editing the JustAliens.params file and edit the signal_parallel line to this: signal_parallel True

2. Locate the path of the downloaded repo e.g. C:\Users\username\Downloads\Aliens-Task-main

3. Edit line 52 in the StimToolLib.py file so that the location points to the inputx64.dll file

   Example: Line 52 would be:

parallel_writer = ctypes.windll.LoadLibrary('C:\Users\username\Downloads\Heartbeat-Counting-Task-main\inpoutx64.dll')

Be sure to edit the path to YOUR correct path location
