Search folder with specific string within the subfolders and display the full name of the folder searched.

I have tried to build a basic code first in searching the folder with '_2D_MDE_TI_' within the subfolder. I've got the correct number of files that have this specific string on it but I can't display the full folder name of the target folder.

The whole folder name is something like ''20170906-50--2C_2D_MDE_TI_240''

Next, I tried using for loop to loop through 300+ folder and save both with and without specific string of the searched foldername, but I'm not sure how I suppose to write it.

The purpose is to check if the subfolders contain this type of folders,

Appreciate it if someone could help me with this.

Thank you

folder = 'C:\Users\Asian Cardiac Lab\Desktop\dicom';

maininfo = dir(fullfile(folder));

maininfo(~[maininfo.isdir]) = [];  %remove non-directories
tf = ismember( {maininfo.name}, {'.', '..'});
maininfo(tf) = [];  %remove current and parent directory.

subdirinfo = dir(fullfile(maininfo.name));
subdirinfo(~[subdirinfo.isdir]) = [];  %remove non-directories
tf = ismember( {subdirinfo.name}, {'.', '..'});
subdirinfo(tf) = [];  %remove current and parent directory.

a = regexp({subdirinfo.name},'_2D_MDE_TI_','match')
len = length(find(~cellfun(@isempty,a)))
a = [a{:}]
