At this moment, my setup consists of OpenBCI Gelfree BCI Cap + PsychToolbox visual trigger code + Emotibit. All streams synchronized via LSL and saved as an XDF File via LabRecorder. Emotibit is just

I am trying to save data from OpenBCI through liblsl-Matlab in Matlab during an experiment in PsychToolbox. I am working with Ubuntu 20.04.1 LTS in a dual boot system, but I am really new to it.

I would like to set up a somewhat basic experiment, wherein I would use PsychToolbox or PsychoPy to present some on-screen stimulus, and then have PsychoPy issue a command to LSL to sync the onset of

I have not done this myself, but here are some thoughts. Psychtoolbox runs in Matlab. You are presenting your stimuli with Psychtoolbox / Matlab. Therefore you will be able to generate markers in the

working memory task. I present my stimuli using psychtoolbox. How do I record\mark event informations (the stimuli that are time-locked to the participant's response and EEG signal modulation while p

Thank you for your kind reply and suggestions. I will have a look to it! Currently I am using LSL in Matlab (because I am connecting my cognitive task programmed with Psychtoolbox and neurofeedback),

With the search link above that finds other psychtoolbox OpenBCI threads, you can contact those individuals by clicking on their usernames. Then there is a button to send a direct message to them.

You can also see some past threads here with questions about Psychtoolbox,

yes, it only a variant of a p300 speller. My software is psychtoolbox based on matlab. I can use a serial port for mark. Do you do this job?
