[Eeglablist] add events to the EEG data

Hello Karlo, Hoping the below helps you a bit to move forward. Cheers, Tarik

Please first review these online tutorial pages if you haven't had a chance
to yet.

http://sccn.ucsd.edu/eeglab/eventtut/eventtut_old2.html

Although there are other ways, you may try these steps:

1. Add an event using the GUI, and use the eegh command to see how you
should script it.
2. Make a matlab loop that runs through the events in your EEG file, and
finds the time of each your A events.
3. For each time from point 3, make a new time that is 1.5 second after
each A.
4. Make a new set of events called A at each of the times you derived at
Step 4.

You may use the "eeg_addnewevents" function in the eeglab distribution,
which should allow you to do step 5 above.

**make sure you have your times in the correct format (e.g, samples or
seconds as necessary for each function)

**in your loop you could write an event each time you find an event 'A' but
it's quicker if you make all the times at once with the eeg_addnewevents
function

**You may also explore other options for loading a text file with times to
be added in as events.
