Error with uigetfile in an Application

Hey There!

I'm a newbie in this forum but I've been using it for a while and it solved a lot of issues I had to fix.

I've designed a UI interface were I had to press a button which made me import a .s2p file and then plot it.

Anyway, I had an issue since it gave me this error:

"Error using rf.file.touchstone.Data/read

Unable to open file 433_26_6.s2p."

I see this error message on the first time I load the file from a different folder than the one of the App.

Then it doesn't occurr....

I'm leaving you the code:

file = uigetfile({'*.s2p; *.s1p','TouchStone Files (.s2p, .s1p)'},'File Selector');

s = sparameters(file)

y = yparameters(file)

figure

rfplot(s, 'real')

figure

rfplot(s, 'imag');

"

Thank You in Advance

I believe that UIGetfile just gets the name of the file that you select, thus you will need to have a line of code just after UIGetfile which says:

file = load(file)

That's what I was looking for!

If you select a different folder in the UIGETFILE dialog, this is not inlcuded in the 1st output, but in the 2nd one:

[fileName, filePath] = uigetfile( ...
    {'*.s2p; *.s1p','TouchStone Files (.s2p, .s1p)'}, ...
    'File Selector');
if ~ischar(fileName)
    disp('User has canceled the file selection');
    return;
end

file = fullfile(filePath, fileName);

Now this is the complete file name including the path.
