[FieldTrip] loading brainvision data

Hello Fieldtrippers,

Hello Fieldtrippers,

For an assignment during my internship at the Radboud UMC, I want try to use fieldtrip for Beamforming at Auditory Evoked Potentials.
However the first step is unsuccesful. I try to load *.eeg , *.vhdr , *.vmrk and *.avr files but I receive multiple errors.

I also tried to use the example script in the tutorial. However this doesn't work either. I get errors like:


??? Error using ==> ft_read_header at 86
file or directory 'heineken000003-kop.eeg' does not exist

Error in ==> trialfun_general at 55
hdr = ft_read_header(cfg.headerfile, 'headerformat', cfg.headerformat);

Error in ==> ft_definetrial at 161
    [trl, event] = feval(cfg.trialfun, cfg);


Especially the directory error pops up frequently. I don't have a clue.
My script is like this:
 
cfg = [];

cfg.datafile     = 'heineken000003.eeg';
cfg.headerfile   = 'heineken000003.vhdr'

cfg.trialdef.eventtype = '?';   

ft_definetrial(cfg)


Can anyone help me? FIY I lack experience of working with EEG and fieltrip, but I work with Matlab regularly.

Hope to hear from you!
