Error in path, although it "exists"

Dear Mathworks,

I am running some code that worked fine under r2017a, but now I am on the prerelease 2019a. I want to load a file from a starting directory, that tests OK with "exist", but when I use uigetfile, I get an error message. Any idea? /Claes Olsson

K>> [fNames, fPath, filterNdx] = uigetfile(...
    {'*.raw', 'Bruker *.raw v.3'; ...
    '*.brml', 'Bruker *.brml'; ...
    '*.*', 'All Files'}, ...
    'Open *.raw File', ...
    'G:\Department\SF\Measurement\SESPC16337\2019\1jan\', 'MultiSelect', 'on');

Error using matlab.ui.internal.dialog.FileSystemChooser/PathParser (line 87)

Prerelease 2019a? Why don't you use the final release instead?

[Steven Lord]

At the time the question was asked (January 2019) the final release of R2019a was not avaiable.

But why was the question raised now?

[Steven Lord]

My guess is that someone posted a spam answer or comment (which made this question one of the "Most recently updated" items) and then that spam was deleted.

Hi Claes,

This works perfectly fine in the final release of MATLAB R2019a. However, I found one mistake in the code shared, the extensions to filter the files should be separated by semi-colon instead of a comma. Given below is the updated code:

[fNames, fPath, filterNdx] = uigetfile(...
    {'*.raw'; 'Bruker *.raw v.3'; ...
    '*.brml'; 'Bruker *.brml'; ...
    '*.*'; 'All Files'}, ...
    'Open *.raw File', ...
    'G:\Department\SF\Measurement\SESPC16337\2019\1jan\', 'MultiSelect', 'on');
