trigger duration mismatch

[aidalynn]

I’m using mne version 1.1.dev0.

I’m trying to get the events from my opm-meg experiment, and one of my triggers is only found when i set min_duration=1e-4, which is way too short.

However, I set the trigger duration to 2.5s in the experiment, it shows up as lasting 2.5s in the behavioural output from PsychoPy, and when I run some code to find the absolute duration of the trigger itself in the data, it also shows as lasting 2.5s. Is it possible that the parallel port failed somehow just to send that specific trigger for the set duration?

Hardware failure is always a possibility. What does the trigger channel look like when you plot it?
