Hello Fieldtrippers,<BR>
<BR>
For an assignment during my internship at the Radboud UMC, I want try to use fieldtrip for Beamforming at Auditory Evoked Potentials.<BR>
However the first step is unsuccesful. I try to load *.eeg , *.vhdr , *.vmrk and *.avr files but I receive multiple errors.<BR>
<BR>
I also tried to use the example script in the tutorial. However this doesn't work either. I get errors like:<BR>
<BR>
<BR>
??? Error using ==> ft_read_header at 86<BR>
file or directory 'heineken000003-kop.eeg' does not exist<BR>
<BR>
Error in ==> trialfun_general at 55<BR>
hdr = ft_read_header(cfg.headerfile, 'headerformat', cfg.headerformat);<BR>
<BR>
Error in ==> ft_definetrial at 161<BR>
[trl, event] = feval(cfg.trialfun, cfg);<BR>
<BR>
<BR>
Especially the directory error pops up frequently. I don't have a clue.<BR>
My script is like this:<BR>
<BR>
cfg = [];<BR>
<BR>
cfg.datafile = 'heineken000003.eeg';<BR>
cfg.headerfile = 'heineken000003.vhdr'<BR>
<BR>
cfg.trialdef.eventtype = '?'; <BR>
<BR>
ft_definetrial(cfg)<BR>
<BR>
<BR>
Can anyone help me? FIY I lack experience of working with EEG and fieltrip, but I work with Matlab regularly.<BR>
<BR>
Hope to hear from you!<BR>
