def present_stimuli(stimuli, settings):
"""Present stimuli in the specified order timed by scanner triggers.
Uses psychopy's launchScan module which adds a test/scan switch on the
first window. If in test mode, launchScan immitates the scanner by sending
triggers (key press '5') and playing scanner noise when the scanner would
be acquiring a volume (if settings['sound'] == True).
The inner function parse_keys() is called regularly to listen for key
presses and update the dictionary of state variables accordingly. The rest
of the function uses various state variables to determine what actions to
take, e.g. play a sound, present a response probe, rest.
Saves the following files in a directory called 'run_data' in the subject
directory.
[subject]_run[run]_all_keys_[date].txt: All key presses recorded
[subject]_run[run]_resp_blocks_[date].txt: Task performance
[subject]_run[run]_stimuli_timing_[date].txt: Stim name and onset time
[subject]_run[run]_settings_[date].npy: settings dict used this run
[subject]_run[run]_stimuli_onsets_[date].npy: Stim name and onset time
[subject]_run[run]_vol_onsets_[date].npy: Onset time of all triggers
An automated log file is also saved in logs/
Parameters
----------
stimuli : ndarray of psychopy.sound.SoundPyo objects
Sounds to be presented in this run in the order in which they are to be
presented. As determined by order.py
settings : dict
