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

Same problem... How did you fixed it?

[Jan]

I have the same error in Matlab 2021a.

Unfortunatelly, previously wokring edfRead by Brett Shoelson is not possible to use :(

[Brett Shoelson]

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

[Isaac Kafshkanan]

I am having a same issue as others

[shams omar]

I have the same error in Matlab 2021a.

How did you fixed it?

[Jennie Rodowicz]

I am having this same error in 2021b

[Rana Hamza]

I have the same error but trying to fix it soon and tell you accordingly

[Brett Shoelson]

Has anyone made an attempt to contact our tech support about this issue, see if they can help?

How can I fix the following problem:

Error using signal.internal.edf.validateEDF

Expected Reserved to match one of these values:

'EDF', 'EDF+C', 'EDF+D', ''

The input, 'BIOSEMI', did not match any of the valid values.

Error in signal.internal.edf.edfinfo (line 27)

Error in edfinfo/readHeader (line 212)

Hi!

I have a similar problem, how did you fix it?

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.

Thank you!

[Luisa de Vivo]

why, when I click on signal.interal.edf.validateEDF no pop-up appears?

[Warwick]

Thank you also, this allowed me to open some semi-broken EDF files that I had been sent which had all sorts of wierd strings in the 'Reserved' header entry.

Brilliant!

You are so Brilliant! thank you very much!
