Hi. I have looked at video and Answers to try to figure this out, and don't seem to have it right.
I have a GUI function that reads an Excel file (picked with uipickfiles , very nice), plots the raw data, and then uses dualcursor (also very nice) to select the appropriate data, and plot that in a separate axis. Good so far. Now, I need to get the windowed data out of the function!
The data is stored in "plot_me".
When I run the following code, I get an error of "Attempt to reference field of non-structure array." Sorry that it is kind of long. There are commented lines that show some of my attempts. Any suggestions are much appreciated. Thank you!

function [out_file,varargout] = scloopgui3(varargin)% SCLOOPGUI3 MATLAB code for scloopgui3.fig
% SCLOOPGUI3, by itself, creates a new SCLOOPGUI3 or raises the existing
% singleton*.
%
% H = SCLOOPGUI3 returns the handle to a new SCLOOPGUI3 or the handle to
% the existing singleton*.
%% SCLOOPGUI3('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in SCLOOPGUI3.M with the given input arguments.
%% SCLOOPGUI3('Property','Value',...) creates a new SCLOOPGUI3 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before scloopgui3_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to scloopgui3_OpeningFcn via varargin.
