Hello everyone, I'm currently running an EEG experiment which lasts around 10-15 minutes and I'm expecting to find changes in slow bands across time (minutes), the issue I'm having right now is that EEGLAB requires events for plotting the ERP spectral power and I'm not interested in ERPs also I don't have at the moment the event file. So, looking for alternatives I've found the Color Density Spectral Array (CDSA) which is used in the ICU to monitor EEG changes throughout many hours and I want to try it in my data to see if it works for my purpose.
So, can anyone tell me how to plot/analyze the spectral array from continuous EEG (10 min) in EEGLAB or MATLAB ? (I'm no expert in programming so a script would help a lot)
