Error using ==> textscan Error

Hi,

I keep receiving the following error: Error using ==> textscan First input cannot be empty with the following code:

function ceaContent = read_textfile(chrPath)
% initialize return-values
ceaContent = {};
try
    %open textfile
    fid = fopen(chrPath);
    Direc = dir(chrPath);

      ceaContent = textscan(fid, '%s', 'Delimiter', '\n', 'whitespace', '', 'bufsize', max(Direc.bytes, 4095)); 
      ceaContent = ceaContent{0};

      ceaContent = ceaContent(~ismember(strtrim(ceaContent), ''));

      fclose(fid);
  catch %#ok<CTCH>
      try fclose(fid); end %#ok<TRYNC>

Thanks for the help!

What is "fid"? Is it empty ...?

[Mick]

It is a file directory(path) and...isn't supposed to be empty

Are you sure, did you check that? The error message you reported looks like fid is empty.
