Hi Angel,<div><br></div><div>I don't know if EEGLAB has built-in functions for this kind of export, but depending on the exact format you need (and whether it needs to be readable by some other software) you can do this on your own using basic MATLAB functions. The EEG data are in a variable called "EEG.data", which should be a 3-dimensional matrix of Channels x Samples x Trials, so you can use some MATLAB script to loop through the trials and for each trial write (to a text file) the voltages, as well as the trial information associated with that trial.</div>

Hi there! I'm Angel Tabullo from Argentina, and I'm new to the list. I wanted to ask if anyone knows how can I export EEG and epoch data from EGGLAB to the same text file. EEGLAB generates a file with the following structure: </div>
