Reading trigger information from EEG data in Real-Time

[Sanchez Alejandra]

Hello,

I am trying to run an experiment in Real-Time, but I am having problems to find the info about the trigger that I sending through a series port. Basically, when I set-up the Lab Streaming Layer in EmotivPro 2.7.1.344, I select EEG. This allows me to stream the EEG data in real time. However, I have no information about the trigger, as I can only stream the first 18 channels (14 sensors + timestamp, etc.).

How can I read the latency of the trigger?

The documentation (Data sample object – Cortex API (gitbook.io)) says that I should have access to MARKER_HARDWARE and MARKERS, but all the fields I can see are COUNTER, INTERPOLATED, EEG and RAW_CQ. The device that I am using (in case it matters) is EPOC X-E2020274.

Thank you!!!

Alex.

Thank you for your question.

At the moment, we do not support the feature to send marker via outlet of EmotivPro LSL. We will support it soon in next version. If you have other questions, please let us know. Kindly provide more information about your projects so we can provide the best solutions for your needs.
