FAQ: How can I force quit an experiment and preserve the collected data?
#1
The preferred way to terminate an Experiment Builder session early is to press Ctrl+C (on Windows) or Cmd+C (on Mac) on the Display PC keyboard. Using this specific command ensures that the EDF file is properly transferred from the Host PC to the Display PC. The saved file will contain all the data that was collected up to the moment you quit.

Note: You may need to press the key combination a few times before it successfully stops the experiment.
