[Eeglablist] How to segment this continuous data into a regular time windows?

[Eduardo Schenberg]

Hello James,

Thank you very much for that. I have a very similar question as Taewon and this seems to work nice. 

However, this code you sent using eeg_regepochs seems to discard previous events created in my EEGLab dataset when I manually selected bad segments of my continuous dataset for deletion (using the standard EEGLab GUI to plot, mark segments and delete). But it is important for me to still know where these events are before, for example, doing FFT on the segmented data

Do you know how to segment data in EEGLab keeping previous events on the dataset?

many thanks

eduardo
