First, load the data into eeglab so it is a .set file.
In your case it seems you have continuous data with no events. The
epoching function available in eeglab requires events in order to
In your case you can use the function pop_regepoch to make those
epochs and/or put in events.
Type help functionname or doc functionname at the command line to get
info on how to use the function, and to make it make 1 second epochs.
Alternatively, you can manually edit event values from the eeglab
menu, and place a new event where you want each of your 10 epochs to
Thanks for your response to confirm that you had success.
basic steps for all eeglab functions are detailed on eeglab tutorials,
powerpoints, summer school presentations that you can easily google.
If you haven't had a chance yet, it is highly recommended that you
practice basic EEG processing steps with the eeglab gui, using eeglab
Like that it is very easy to learn how to do basic eeg processing
steps with eeglab.
if you want to "import" events into the .set file, Google past
eeglablist posts and review eeglab tutorials on events information
