Dear Group and EEGLAB members,

Hope you are doing well.
We are using a g.tec device to acquire EEG data. We are sending triggers
through a parallel port. We are able to get EEG data with all trigger

When we are importing an eeg data file into EEGLAB all triggers values are
not visible. Event type option showing some trigger values. Trigger values
are in raw eeg files. Some numbers (triggres) are not visible when
selecting the events option in eeglab gui.

Do we need to set trigger values in any fixed bracket of numbers? As for
one event when i am setting 9, eeglab is not detecting but when i am
changing 9 to 90 it is showing in eeglab.

We would be really thankful if you could send some relevant
supporting material.

Thanks in advance. Regards

Thank You
