Hello Cedric,

Thank you for your response.

We are using the EEGLAB toolbox to analyse eeg data.

run " EEG.event"

output :

ans =

  1×2337 struct array with fields:

    type
    latency
    urevent


EEG.event.latenciess shows  2337 values
some values that it shows

ans =
     1694857

ans =
     1695210

ans =
     1695854

ans =
     1695898


There are values given when selecting the even values option in the edit
section. There is event type and latency (sec) is given for each 2337 event.


Regards
Jay Prakash
