This tutorial is designed to outline the steps in MATLAB for a simple FFT analysis without ocular correction.
First, you need to download and unzip the sample data that is HERE and the channel locations file which is HERE. You need the doFFT.m function found HERE. You will also need the folder HERE in your MATLAB path as it has the functions need to load the data. Finally, you will need to install EEGLAB which is available HERE.
Now you will be able to run a simple FFT analysis using the code HERE. The analysis does not include a correction for ocular artifacts - luckily, this data is pretty clear and blink free. If all goes well you should see the plot below, a nice single subject FFT analysis that shows more power for oddball as opposed to control trials in the lower frequency bands.
