Extracting values from fields in app designer

I am trying to figue out how to obtain the values from certain fields within my struct in app desginer.
I would like to pull the struct from a .mat file.
I first am using:
properties (Access = private)
Mystruct % Description
end
properties (Access = public)
end
methods (Access = private)
function Start(app)
Mystruct=load('AccelQuery.mat')
end
end
Then I should be able to use app.Mystruct in my callback function to load the struct. Any suggestions on obtaining the values from certain fields such as SERIAL_NUMBER?

If a .mat file is meant to contain a single structure variable, but "save"d without using the "-struct" option, you'll have to access the struct by invoking the name of the original structure's variable. So if I have
S.a = 1
S.b = 2
S.c = 3
save("testdata.mat","S")
To access the fields a, b, c from loaded data, I need to do
loadedS = load("testdata.mat")
loadedS.S.a
If you want to be able to do
loadedS.a
then you have to save as
save("testdata.mat","-struct","S")
Maybe that's what Sourabh is going to check...

Hi,
@J.Alex Lee is right in suggesting what I was going to check.
If his comment still does not solve the issue, please upload the 'AccelQuery.mat' for me to cross check.
