The problem is here:
i assign the directory as A1 having after having converted it to a string
You did not provide the code you use for this. But the error message is clear: fullfile requires a char vector, not a modern string object.
Folder = '/Users/username/Desktop/data/'; % As char vector, not as string
FileList = dir(fullfile(Folder, '*.txt'));
for k = 1:numel(FileList)
File = fullfile(Folder, files(k).name);
data = readtable(File, 'FileType', 'text', ...
'Delimiter','tab','TreatAsEmpty', ...
{'UND. -60001', 'UND. -2011', 'UND. -62011'});
%do stuff
end
In modern Matlab version the folder is replied by dir also. Then this works also:
File = fullfile(files(k).folder, files(k).name);
Is there a way to use/get around the read table TreatAsEmpty argument
with a string input and use fullfile?
Neither readtable nor the 'TreatAsEmpty' argument has been the problem, but exactly as the error message told you, only the input argument of fullfile.
