Thank you all for your fast responses!
The problem was solved. My directory set-up was incorrect. The data was unable to be loaded because I filed this in a subfolder. I place all data loose (not in a subfolder), in the same directory were I have my script.
Again, thanks!

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!

Hi Brian,
Are you in the correct directory? In other words is your 'pwd' such that you can see the files when you type 'dir'?

Hi Brian,
Also I noticed in your error you have '-kop' in the file name but not in the
dataset name. I've noticed that one can't change the file name of .eeg
files (e.g. copying them to a new file name) and then still load them; you
should stick to the original name as it was given when collected.
Best,
Johanna
