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>
