This is a modification of the File Exchange submission "edfread" for importing an EDF file into MATLAB. I removed a few options which enable import of large files to occur much, much faster in the case of 1-sample records or records containing all of the samples at once.
[hdr, dataMat] = edfread2(fname)

Reads data from ALL RECORDS of file fname ('*.edf'). Header information is returned in structure hdr, and the signals (waveforms) are returned in dataMat, which is either a (samples x channels) matrix, or a (1 x channels) cell array full of (samples x 1) arrays IF there are different numbers of samples in each channel.

Hi Matt,
same error as Fasil. Could you please comment?
thanks

Hai Matt
I got an error in the following line

writeIndices{chans} = writeIndices{chans} + hdr.samples

Error using +
Matrix dimensions must agree.

Hi Matt

I met the error as follows:
Subscript indices must either be real positive integers or logicals.

Error in edfread (line 122)
hdr.label{ii} = regexprep(fread(fid,32,'*char')','\W','');

I record the EDF file with Eyelink, a eye tracing system.

Do you have any solution?
