How to solve error with data file

Hello

I have a problem with the date files I've acquired from an audio-visual experiment.

audios = [0 1 2 1 2];
modes = [0 1 1 2 2];

DataFile = ls('a.mat','b.mat','c.mat','d.mat','sample.mat');
nRun = size(DataFile, 1);

I get error sign like this.

Error: AVtranslate_practice (line 11) S = load(deblank(DataFile(df,1:nRun)), 'gvals');

and that it cannot find the directory and files. Could you help me out on this problem?

Thanks!

Check whether the file name created is existing in the current working directory.

Read the below links to process sequence of files: https://www.mathworks.com/help/matlab/import_export/process-a-sequence-of-files.html

Make sure you denote the right format of the file

What does ls() return? A cell array? A number.

Try this:

filename = deblank(DataFile(df, 1 : nRun))
fprintf('filename = %s\n', filename);
if exist(filename, 'file')
    message = sprintf('%s exists!', filename);
    uiwait(helpdlg(message));
else
    message = sprintf('%s does not exist!', filename);
    uiwait(warndlg(message));
end

What do you observe?
