Re: Error invalid concatenation of cell array with matrix

[Wang S]

Hi Syed,
 
Oh, from your code:
if ~exist('ignore_dirs', 'var')
    ignore_dirs = {};
end
I guessed that the variable "ignore_dirs" was a cell (in a {}),

but this error message suggests that the variable "ignore_dirs" was a string 
(in a '' or ""), not a cell (in a {}) ?

If "ignore_dirs" was a string, possible solution may be:
if ~exist('ignore_dirs', 'var')
    ignore_dirs = '';
end
ignore_dirs_full = {'.','..',ignore_dirs};

Hello Wang

  I made the modification but seem to get the following error. I am also 
showing the program
octave:1> LIDC_process_annotations.m
error: sq_string cannot be indexed with {
error: evaluating argument list element number 3
error: called from:

octave:1> quit



if ~exist('ignore_dirs', 'var')
    ignore_dirs = {};
end
ignore_dirs_full = {'.','..',ignore_dirs{:}};
  dirData  = dir('/home/syedk/PAC/DATA/XML/tcia-lidc-xml/');      %# Get the 
data for the current directory
  dirIndex = [dirData.isdir];   %# Find the index for directories
  fileList = {dirData(~dirIndex).name}';  %# Get a list of the files

  mat_ind = cellfun(@(x) strcmp(x(end-3:end), extension), fileList, 
'UniformOutput', true); % FIND XML FILES
  fileList = fileList(mat_ind); % keep only XML files

  if ~isempty(fileList)

      fileList = cellfun(@(x) fullfile(dirName,x), fileList, 'UniformOutput', 
false);  %# Prepend path to files

  end

  subDirs = {dirData(dirIndex).name};  %# Get a list of the subdirectories
  validIndex = ~ismember(subDirs, ignore_dirs_full);  %# Find index of 
subdirectories
                                               %#   that are not '.' or '..'

Hi Syed,

I'm sorry that maybe I hadn't express it clearly in the previous email.

I've just see your attachment "find_files.m". The line 46 in your file is
ignore_dirs_full = "{'.','..'},ignore_dirs(:));"

It seems that it was wrong and it maybe should be
ignore_dirs_full = {'.','..',ignore_dirs{:}};

And I think you could CC the emails to the "address@hidden" too,
so that maybe more supporters and helpers will help you in time.
