issue with ITIs #839
Description
ITIs are not 1s as DEAD_TIME parameter has no effect.
here's the actual dead time inbetween state machine runs:
this code in iblrig.base_choice_world._run() does nothing:
# handle ITI durations
if trial_number > 0:
# The ITI_DELAY_SECS defines the grey screen period within the state machine, where the
# Bpod TTL is HIGH. The DEAD_TIME param defines the time between last trial and the next
dead_time = self.task_params.get('DEAD_TIME', 0.5)
dt = self.task_params.ITI_DELAY_SECS - dead_time - (time.time() - time_last_trial_end)
# wait to achieve the desired ITI duration
if dt > 0:
log.debug(f'Waiting {dt} s to achieve an ITI duration of {self.task_params.ITI_DELAY_SECS} s')
time.sleep(dt)- Add unit test for time.sleep
- Communicate to users beforehand how this will affect training/animal performance
- Add warning about ITI < 0.5
