I am a new user of StimTracker by Cedrus. At the research center where I currently work, StimTracker is used together with the EEG system in order to align behavioral-stimuli recordings with EEG recordings. I’d like to use StimTracker on its own—to record precise stimulus onsets and offsets via a photodiode and/or microphone—without launching the EEG software. Right now I’m running the EEG system with empty channels, which works but isn’t ideal since I’m not actually acquiring EEG data. Could you recommend a standalone setup?
If the EEG system is not recording the data, another option is to have a computer do it. StimTracker (Duo or Quad models, but not the original model) can produce time-stamped output via USB.
Would this feature interest you? I can provide more details if it does.
Hello again,
Thank you very much for you answer, Hisham. We are using the StimTracker Duo. I’d thus like to get more info on how to produce time-stamped output via USB, as you suggested.
Hello Ana Luísa, please see this page, Enabling USB Output. Make sure to read the last few lines about resetting the built-in timer:
The data that StimTracker sends via USB is time-stamped. You can send a command via USB to reset the timer, but additionally (or instead), you can also have StimTracker automatically reset the timer based on a signal, e.g. onset of light sensor 1. To enable this, click on the desired signal and enable the option Reset timer on signal onset.
