Hello community,
I have a simple problem. I want to prompt the user to enter a directory name, check if it exist. If it does, store that fullpath into my guidedata. If it doesnt, create the directory and also 2 subdirectories within that directory then store fullpath into guide data. The name of the directory I want to search and create folders in is named 'Labelers.' It's fullpath is C:\Users\ecorbett\Documents\MATLAB\Labelers So far I have this code:
prompt = {'Enter Labeler Name:'};
dlg_title = 'Labeler Name';
num_lines = 1;
answer = inputdlg(prompt);
if isempty('Labelers'(answer))
mkdir('Labelers','answer')
else
handles.name = answer;
guidata(gcf, handles);
handles = guidata(gcf);
end
It's not working thus far. Any advice will be greatly appreciated!

Why don't you just call uigetdir to let the user specify a folder and create one if needed? The "New folder" button is right there on the dialog box.

Hmmm, hadn't considered that option. I suppose that would have been easier.

root = 'C:\Users\Oleg\Desktop\';
answer = inputdlg(prompt);
if isempty(answer{1}) || exist([root answer{1}],'dir') ~= 7
mkdir(root,'answer')
else
handles.name = answer;
guidata(gcf, handles);
handles = guidata(gcf);
end

if exist(answer{1},'dir')~= 7
%the line below works, but the lines to create the subfolders dont
mkdir('C:\Users\ecorbett\Documents\MATLAB\Labelers',answer{1})
mkdir(['../' answer{1} '/Labels'])
mkdir(['../' answer{1} '/Segmentation'])
