Why does the function call "function [hdr, record] = edfReadOddur( 'tinnaprim​e.edf',var​argin )" give an error?

This is the error message:
Error: File: edfReadOddur.m Line: 1 Column: 40 Unexpected MATLAB expression.

Oddur - if your function signature (the first line in edfReadOddur.m) is written as
function [hdr, record] = edfReadOddur( 'tinnaprime.edf',varargin )
then the problem is that you are trying to set the first parameter of your function as a string rather than as an input parameter/variable. Your signature should be defined as
function [hdr, record] = edfReadOddur( filename, varargin)
and you would call the above (from the command line or another piece of code) and pass in 'tinnaprime.edf' to populate/set the filename parameter
>> edfReadOddur('tinnaprime.edf')
See Function Basics for more details.

Oddur - from edfRead at FEX, the function signature is
function [hdr, record] = edfread(fname, varargin)
so it isn't clear to me why you think that it should be
function [hdr, record] = edfRead('tinnaprime.edf', varargin)
You would call this function as
[hdr, record] = edfRead('tinnaprime.edf)
(perhaps passing more input variables as described along with this FEX submission.
As for the error, No such file or directory, try passing the full path and file name as the input parameter to edfRead.

Again I tried to take your suggestions into account. I used the following function signature:
function [hdr, record] = edfReadUntilDone(tinna, varargin)
I called the function with:
edfReadUntilDone('C:\Users\Oddur\Documents\Emotiv Files\Tinna\tinnaprime.edf')
I got the following answer:
ans =

ver: 0

digitalMax: [1×40 double]
prefilter: {1×40 cell}
samples: [1×40 double]

From this I gather that the file has been loaded. I do unfortunately not get any data records.
The original question that I posed has now been answered so I shall accept your answer. The rest of the problems I have with the function I shall take up with Brett.
Thank you.
