Pause code while importing data

Hello everyone,

I'm developing a code that will allow the user to imprt whatever data using uiimport command. The data that this code will see will always have the same variables but the problem I run into is that once the data is imported, the code (I think) is not recognizing anything and throws errors. I think the code is continuing to run while the user is importing data which wouldn't allow matlab to see the variables imported.

I am thinking that having an option to run the code at a strategic point will solve the problem but I'm having no luck.

I currently have:

clear;
clc;
uiimport('-file')
while (1)

m=input('Do you want to continue, Y/N [Y]:','s')
if m=='N'
break
end

end

Using an output of uiimport will stall execution of later code.

S = uiimport('-file')
disp('Import finished.')

% and check for the existence of the fields
needed_var = 'X' ;
if ~isfield(S, needed_var)
  error('You should have imported a variable named "%s".', needed_var)
end
disp('Import succeeded') ;

When I run what you have written up, I get an error saying: Undefined function or variable 'S'.

Do you know why it sends this error?

Could you confirm that you have the line

S = uiimport('-file')

Confirmed. I will attach a screenshot as well. Would running 2014a cause this issue?

First: fix the lowercase S /capital s !!

The error seems to arise from uiimport having problems importing the data properly and has little to do with my code.
