Select specific files from subfolders

Hi! I performed experiments and want to plot certain experiments together in 1 plot. Every experiment is saved in a different subfolder of the "main folder". The subfolders are named after the codes of the experiments. Now I want the code to select for example the subfolders of tests C3, C6, C8 and C9 specifically. On internet I found how to select all the files of a certain extension in all the subfolders (filePattern = fullfile(pathname, '**/*.asc'));, but now I want the script to only look at a few subfolders. Does anyone know how this can be done?

i suggest you simply remove those entries which do not contain the folder names you are interested in

It would also be possible to read in all of the subfolders, and then pick the ones you want based on some comparison. I.e. make a string array of the experiment codes you want, and just find those.

codes = {'C3','C6','C8','C9'};
filelist = dir(pathname);
filelist = filelist(ismember([filelist(:).name]==codes));

I don't think that bit is going to work right out of the gate, but it should give you an example of what I mean.

Folder = 'C:\Your\Folder';
SubFolderList = {'C3', 'C6', 'C8', 'C9'};
for iSub = 1:numel(SubFolderList)
   File = fullfile(Folder, SubFolderList{iSub}, 'YourFile.mat');
   Data = load(File);
   ... what to do now?
end

Or:

DirList  = dir('C:\Your\Folder\**\*.mat');
SubSet   = {'C3', 'C6', 'C8', 'C9'};
FileList = fullfile({DirList(:).folder}, {DirList(:).name});

% Find all files, which contain '\C3\' or '\C6\', ...
Selected = contains(FileList, strcat(filesep, SubSet, filesep));
