Error using evalc Unrecognized function or variable 'edfmex'.

Hi I am trying to use a batchFileConverter function to convert edf to .m file format.

function batchFileConverter_Dataset1()

sourceFolderName = './rawData/';

destFolderName = './matlabData/';

rawFiles = dir([sourceFolderName '*.edf']);

nFiles = length(rawFiles);

% Disp file information:

printToConsole('L1');

printToConsole(1, 'Processing %i files...\n', nFiles);

% Loop through files:

for fileIndx = 1:nFiles

edfDataConverter([sourceFolderName rawFiles(fileIndx).name]...

,[destFolderName rawFiles(fileIndx).name(1:end-4) '.mat'])

printToConsole(2, 'Done with file %i.\n',fileIndx);

end

printToConsole(2, 'Done with folder.\n');

printToConsole('L2');

end

%% edfDataConverter Function:

function edfDataConverter(edfFilename,matFilename)

% edfDataConverter Converts a single edf file to a matlab file.

% Read raw edf file:

hMex = @edfmex; %#ok<NASGU>

[~,rawEDF] = evalc(['edfmex(''' edfFilename ''');']);

The errors are:

Unrecognized function or variable 'printToConsole'.

Error in batchFileConverter_Dataset1 (line 49)

printToConsole('L1');

Error using evalc

Unrecognized function or variable 'edfmex'.

Error in batchFileConverter_Dataset1>edfDataConverter (line 71)

[~,rawEDF] = evalc(['edfmex(''' edfFilename ''');']);

Can someone tell me how to solve this problem? Thank you!

Hi Qianhui,

I understand that you are facing errors about the unrecognized functions: "printToConsole" and "edfmex".

Since the code is from this GitHub repository: Pupil Size, these are helper functions added by the developer and are not built-in MATLAB functions.

I suggest you load the all the other files in this repository and then try to execute the script. You should not be facing any errors thereafter.

I hope this helps!
