Use string as a path

Hello,

i want to use strings from a cell array as path. How can i do it?

I want to write a code, that loops over all my subfolders. The path to the folders are in my cell-array.

My code are:

if true
  % code
dirs=regexp(genpath(currentpath),['[^;]*'],'match');
size_dirs=size(dirs);
for i=1:size_dirs(1,2)
data=dir([dirs(1,i),\*.tsv']); <<< here i want my subfolder from the cell-array in dirs!!
anzahl=numel(data);
.. do something

end

The error is: argument must contain a string. But in my cell-arrays are only strings :( can someone help??

No.. dirs is a cell array of strings.

Type whos and you will see

dirs                                                        1x28             7098  cell

modify your code slightly to

data=dir([dirs{i},'\*.tsv']);

to make it work.

fullfile is slightly smarter than concatenating with a hardcoded file separator - this considers different operating systems and folders like "C:\" :

data=dir(fullfile(dirs{i}, '*.tsv'));
