I try to analyze EEG using eeglab, but I an event error and ask a question.

An experiment was conducted through E-prime and a trigger was issued according to the event time.

The data stored on the eeg device is then converted into an EDF file to open in eeglab.

Whe I opened the file, I found that in addition to the event value I put in, there was an event balued valled boundary regularly.

The sampling rate of the EEG device is 500Hz, and it is confirmed that the event is generated once a second to match the 500.

From the beginning, this problem did not appear in the EEG device that generates EDF files.

Is this situation due to file conversion?

If anyone has experienced such an error, I would appreciate it if you could tell me how.

I look forward to hearing from you soon.

Thank you.
