How to use only specific files in directory in GUI?

Hello all.

I have a GUI function that can open a directory/folder of images. What I would like to do is actually only select the files/images with the word "PU" in their titles. How would I be able to do this/approach this problem?

Thank you.

Are you using a special file picker, the builtin uigetfile, or dir to get file names?

It is using uigetdir, yes. Within that folder/directory, I want to open only specific images with the title "PU".

folder   = uigetdir('Choose a folder');
List     = dir(fullfile(folder, 'PU*.*'));
FileName = fullfile(folder, {List.name});
for iFile = 1:numel(FileName)
    File = FileName{iFile}
    ... now open it
end

Not sure what you mean by 'select', but you can show a user only the files containing 'PU' in their titles using

[fileName, pathName] = uigetfile('*PU*', 'This is my dialog title', 'MultiSelect', 'on');

In the GUI, I have a "Select Directory" button. This button pulls up all of the images/files in that directory/folder onto the GUI. I only want this button to choose (or "pull up" on the GUI) files with "PU" in the title.
