Filter a directory and add in listbox only files with TIF/TIFF and containing a certain String

Hello, I am trying to list all tif images ina folder into a listbox. I have it working but am trying to now only list those tif files that also contain a string in their name:

I initially choose the first file (using uigetfile so have the extension, path and filename)

             %List all tif images into the list box.
             [pathstr,name,ext] = fileparts(openpath); 
             filePattern = fullfile(pathstr, ['*',ext]) 
             
             myFiles = dir(filePattern);

             ListOfImageNames = {}; % Initialize
             for Index = 1:length(myFiles)
                % Get the base filename and extension.
                baseFileName = myFiles(Index).name;
                [folder, name, extension] = fileparts(baseFileName);
                % Examine extensions for ones we want.
                extension = upper(extension);
                switch lower(extension)
                    case {'.tif','.tiff'}
                        % Keep only  JPG, TIF, or tiff image files.
                        ListOfImageNames = [ListOfImageNames baseFileName];
            %         otherwise
                end
             end

        % Now we have a list of validated filenames that we want.
        % Send the list of validated filenames to the listbox. %ListOfImageNames;
        app.ListBox.Items=ListOfImageNames;     
        

So I thought if I have a string 'NameFilter', then all I need to do is change

        filePattern = fullfile(pathstr, ['*',ext]) 

To

        filePattern = fullfile(pathstr, [Namefilter,'*',ext]) 

But its not quite working. so to summarise, I only want tiff files which contain the string NameFilter

Thanks

   pathstr = fileparts(openpath);
   myFiles = dir(pathstr);
   filenames = {myFiles.name};
   mask = endsWith(filenames, {'.tif', '.tiff'}, 'IgnoreCase', true);
   ListOfImages = filenames(mask);

So simple! Thankyou

Ajh, the only thing is that the string I want the files to contain (Namefilter) is always at the front of the string

[Walter Roberson]

mask = mask & beginsWith(filenames, Namefilter);

With or without the 'IgnoreCase' option as appropriate.
