Hello,

 

I am a new fieldtrip user and would like to know how to read brainvision
files that were exported as .dat into matlab with fieldtrip. It would be
great to read segmented and/ or continous data into matlab that was
preprocessed (artifact correction, ...) in brainvision analyzer. I tried
read_data in combination with the read_header function and I always get
this message:

 

??? Error using ==> zeros

NaN and Inf not allowed.

 

Error in ==> read_brainvision_eeg at 89

  dat = zeros(endsample-begsample+1, hdr.NumberOfChannels);

 

Error in ==> read_data at 686

    dat = read_brainvision_eeg(filename, hdr.orig, begsample,
endsample);

 

Error in ==> ReadAnalyzerSegments at 7

data = read_data(filename);

 

Thank you in advance and best wishes,

Roman
