Re: Error invalid concatenation of cell array with matrix

[Wang S]

Hi Syed,

The following code is not correct
ignore_dirs =";
 
It should be
ignore_dirs = '';
or you can also write as
ignore_dirs = "";
ignore_dirs = [];

You can use "copy and paste" from email to your .m file to avoid error,
for example in the email '' may look like " which may lead to an error.

Hello Wang
Many thanks for your patience and great responses.

The program does the following:

Recursively finds files in a directory structure
  dirName = starting directory (root)
  extension = extension of files to look for
 ignore_dirs = (optional) if there are any directory names to exclude
   (cell array of strings)



  I am getting a syntax error as in

octave:1> LIDC_process_annotations.m
error: unterminated string constant
parse error near line 45 of file /home/syedk/OCT/LIDC/find_files.m

  syntax error

>>>     ignore_dirs ="; 
                        ^

error: called from:
error:   /home/syedk/OCT/LIDC/LIDC_process_annotations.m at line 113, column 11


My code snippet is

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 dat
a for the current directory
  dirIndex = [dirData.isdir];   %# Find the index for directories
  fileList = {dirData(~dirIndex).name}';  %# Get a list of the files

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

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,

  fileList = fileList(mat_ind); % keep only XML files

  if ~isempty(fileList)

  end

                                               %#   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.

Regards,
Wang S
