EDFread giving an error Error using signal.int​ernal.edf.​validateED​F

Error using signal.internal.edf.validateEDF (line 55)
Expected Reserved to match one of these values:
'EDF+C', 'EDF+D', ''
The input, 'EDF', matched more than one valid value.
Error in edfread (line 113)
signal.internal.edf.validateEDF(filename, fileInfo, version, startDate, startTime,...
MatLab wont let me attach a file as edf so I have put it into a zip file. I cannot edit the file and when I used the public function it shortens the signal. I cannot edit the edfread function as it is an internal function. A work around would be greatly appreciated.
Thank you very much for your support
Regards,
Scot

Why is the previously working edfRead by Brett Shoelson no longer possible to use?

This relatively simple addition to the file validateEDF.m fixed this problem for me:
When I tried to read/load an EDF file using the edfread function I got the same error as OP:
Solution:
  1. Click on the underlined signal.interal.edf.validateEDF in the "Error using singal.internal.edf.validateEDF" error message displayed in the Command Window panel. A pop-up box/window will appear.
  2. In the upper right of the pop-up window that appears, click on the underlined View code for signal.internal.edf.validateEDF. The code file validateEDF.m should appear in the Editor panel.
  3. Scroll down to lines 70/71. This is the line of code that is resulting in the error.
  4. Change the second argument of the validatestring function from {'EDF+C', 'EDF+D', ''} to {'EDF', 'EDF+C', 'EDF+D', ''}
  5. Save the file validateEDF.m. A pop-up window may appear saying "validateEDF.m" is read only. Click on Overwrite for the changes to take effect.
Now, lines 70 and 71 of the file validateEDF.m should look like this:
This fixed the issue for me, and I was able to read EDF file contents using the edfread function. I primarily work in Python, so please take my MATLAB advice with grain of salt.
