Use string to define path for uigetfile

I am trying to use a string to define the path for uigetfile in matlab GUI. But I can't get it to work. The uigetfile does not use the my string as path. What am I doing wrong?

Here the code I am trying.

pwd={'C:\Users\xxx\Documents\DTU\SAXS\'};

[filename, dirname] = uigetfile(fullfile(pwd,'folder1','*.txt'),'select file')

There are two methods:

% Folder is not a cell string and not the name "pwd":
Folder = 'C:\Users\xxx\Documents\DTU\SAXS\folder1';
[filename, dirname] = uigetfile(fullfile(Folder, '*.txt'), 'select file')

This does not work if you want to provide a list of accepted file extensions. Then you can specify the initial folder as 3rd argument:

Folder = 'C:\Users\xxx\Documents\DTU\SAXS\folder1';
[filename, dirname] = uigetfile({'*.txt', 'Text-files (*.txt)'; ...
                                 '*.asc', 'ASCII files (*.asc)'; ...
                                 '*.*',   'All Files (*.*)'}, 'select file', Folder)
%                                                                            ^^^^^^

Hi JB, the following code worked well for me. Try it and let me know if work for you.

pwd='C:\Users\xxx\Documents\DTU\SAXS\';
[filename, dirname] = uigetfile('C:\Users\xxx\Documents\DTU\SAXS\*.txt','select file')

Make sure that the string are not cell variables and also that the path your are sending exist.

Hi Arthur. Your gode is working fine, but I would like to use the pwd string in the uigetfile instead of writing the whole path again: uigetfile('C:\Users\xxx\Documents\DTU\SAXS\*.txt','select file')

pwd = 'C:\Users\xxx\Documents\DTU\SAXS\';
[filename, dirname] = uigetfile( fullfile(pwd,'*.txt'), 'select file')

Hi Walter. I tried your code but I does not use the pwd as starting point. When I use:

[filename, dirname] = uigetfile('C:\Users\xxx\Documents\DTU\SAXS\*.txt', 'Select file');

it is working fine.

Do not use "pwd" as name of a variable, because it is a built-in function. Such "shadowing" causes unexpected behavior frequently.

The code I suggested works with Mac.
