MATLAB: Error using copyfile No matching files were found.

copyfileno matching files were found

Dear Matlab users,
I'm very new in Matlab, what am I doing wrong? The tif-files are in the folder TimePoint_1 … Can anyone help me out please?
% copy all tif files without thumb in filename to folder B
path1 ='C:\Users\rename_microscope_files\movie\2019-08-28\32534\TimePoint_1'
dest = 'C:\Users\rename_microscope_files\image_sorted'
source =fullfile(path1,'*.tif');
myfile= dir(source);
% loop over all files in the folder
for i = 1:numel(myfile)   
    idx = strfind(myfile(i).name,'_thumb'); 
    if ~isempty(idx)
        %do nothing
    else
        %copy to folder image_sorted
        copyfile(myfile(i).name,dest)
    end    
end
Error using copyfile. No matching files were found.

Best Answer

I'd replace 
    idx = strfind(myfile(i).name,'_thumb'); 
    if ~isempty(idx)
        %do nothing
    else
by the simpler
if ~contains(myfile(i).name, '_thumb')
which does the required work inside the if.
The problem is that you only pass the filename of the source to copyfile so it looks for it in the current directory, not in path1. The fix is simple:
if ~contains(myfile(i).name, '_thumb')
    copyfile(fullfile(path1, myfile(i).name), dest);
end
