[FieldTrip] Reading in .bdf data into FieldTrip

[Xavier Vrijdag]

Hello Kyla,

I use a BioSemi system as well. I import my bdf data with higher-level Fieldtrip functions, see the example below. You can also find additional information on the fieldtrip website: https://www.fieldtriptoolbox.org/getting_started/biosemi/


        cfg.dataset = [filepath filename];

        cfg.channel    = 1:34;

        cfg.reref      = 'yes';

        cfg.refchannel = 'EEG'; % average of all EEG channels

        cfg.demean     = 'yes';

        cfg.detrend    = 'yes';

        data = ft_preprocessing(cfg);

regards,

Xavier

Subject: [FieldTrip] Reading in .bdf data into FieldTrip

Hello,

I'm trying to load data with a .bdf file extension into Matlab. I have the FieldTrip installed and added to my path. However, when I try reading in the data using the ft_read_data function, I receive an error message of "unsupported header format "unknown".

The data are continuous EEG data recorded from BioSemi in ActiView.

Sincerely,
