What are you trying to achieve?:
Hi, I’m planning to run an experiment with EEG (using BrainVision/ActiCap) and my participants will be watching movie clips. I would like to send triggers on specific movie frames (I have an excel with all the frames and timings that I’m interested in for each clip). I prefer to send them to directly to a frame as I am interested in specific frames so it seems more precise/objective than timings. I’ve found lots of information on how to send triggers via parallel port based on a certain condition (e.g. response), but how do I specify that I want to send the trigger to the particular frames from my conditions file? Can this be done with the builder? Thank you very much in advance!
