<div dir="ltr">dear Sirs<br><br>concerning the necessity to specify a reference while
importing BDF into EEGLAB, do I have to do it exactly when I import it ?
or con i reference later ?<br>my final aim is to apply a common average reference<br><br>can I do this:<br><br>EEG = pop_biosig(input_file_name, 'importannot','off');<br>EEG = pop_reref(EEG, [reference],'keepref','on');<br>
<br>or i strictly HAVE to do this:<br><br>EEG = pop_biosig(input_file_name, 'importannot','off', 'ref', XX);<br>EEG = pop_reref(EEG, [reference],'keepref','on');<br><br>Another
question, is it advisable to first convert BDF to EDF with the Biosemi
converter this in order to (as written in another list post) "avoid
using an aggressive 1hz filter against the BDF offset"<br><br><br>thanks in advance<br>regards<br>Alberto</div>
