import BDF into EEGLAB

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

Hi Alberto,

Did you ever find an answer to your question? We are new to BDF analysis in EEGlab and are also wondering whether we MUST import BDF data with a reference in order to maximize SNR, or whether referencing can be done after importing.

Any suggestions would be greatly appreciated!

Hi everyone,

Did anyone manage to get an answer to this question? I am also interested in understanding better how to process the Biosemi data with EEGLAB.

THanks!
