[Eeglablist] Save EEG epochs in different files

[Stephen Politzer-Ahles]

Dear Alberto,

I don't think there's a built-in EEGLAB function for this, but it will be
straightforward to do with basic MATLAB functions. Just depends on the file
format you want. An EEG epoch is just a matrix of numbers (for example, if
you had 30 channels and sampled at 1000 Hz, then a 2-second epoch is a
30x2000 sample matrix). MATLAB has functions like dlmwrite() that can be
used to write a matrix out to a text file. After that it's just a matter of
putting the function in a for loop to save each epoch one at a time.

Best,
Steve
