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>
<br>
