edfread and edfinfo throw an error

When using edfinfo and edfread with some files (the other files are OK) an error pops up as shown below:

>>edfinfo('S002R06.edf')

Index exceeds the number of array elements (0).

Error in signal.internal.edf.readAnnotations (line 34)

d_idx = find(temp(1:o_idx(1)) == char(21));

Error in edfinfo/readHeader (line 239)

tempDuration] = signal.internal.edf.readAnnotations(tAnnotations);

Error in edfinfo (line 173)

obj = readHeader(obj, filename, fid, fileInfo);

I'm also obtaining the same error when using edfread on files provided in Abdominal Fetal ECG database, but only on record r01. The remaining four records load fine.

Have you found a solution yet? How do you read that file?

Hello,

I also had the same problem and I couldn't solve it. But I could open.edf file with brainstorm. You can add it matlab with add-ons . When you run brainstorm() It will ask account you can create new account then you can open the GUI. In file section create new protocol and create subjects.You can find more information here .
