import BDF into EEGLAB
Posted: Mon Nov 11, 2013 11:15 am
dear Sirs
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 ?
my final aim is to apply a common average reference
can I do this:
EEG = pop_biosig(input_file_name, 'importannot','off');
EEG = pop_reref(EEG, [reference],'keepref','on');
or i strictly HAVE to do this:
EEG = pop_biosig(input_file_name, 'importannot','off', 'ref', XX);
EEG = pop_reref(EEG, [reference],'keepref','on');
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"
thanks in advance
regards
Alberto
