EEGLAB is a rich toolbar for MATLAB to processing EEG data. It can apply ICA (Independent Component Analysis), importing channel locations, artifact rejection and time-frequency analysis. (EEGLAB, 2009)

While recording offline data using Emotiv’s product is used and EEG data is monitored at the same time.

Recorded data is saved in edf format, so it can be converted other formats such as csv or text files. I used to work with MALAB while working with recorded data.

EEGLAB is save this file on the workspace on MATLAB, so it can be saved or used in MATLAB directly. This is very useful to improve algorithms on MATLAB because it is easier to implement algorithms.
