+function varargout = vs_ManualData(varargin)
+% VS_MANUALDATA M-file for vs_ManualData.fig
+%      VS_MANUALDATA, by itself, creates a new VS_MANUALDATA or raises the existing
+%      singleton*.
+%
+%      H = VS_MANUALDATA returns the handle to a new VS_MANUALDATA or the handle to
+%      the existing singleton*.
+%
+%      VS_MANUALDATA('CALLBACK',hObject,eventData,handles,...) calls the local
+%      function named CALLBACK in VS_MANUALDATA.M with the given input arguments.
+%
+%      VS_MANUALDATA('Property','Value',...) creates a new VS_MANUALDATA or raises the
+%      existing singleton*.  Starting from the left, property value pairs are
+%      applied to the GUI before vs_ManualData_OpeningFcn gets called.  An
+%      unrecognized property name or invalid value makes property application
+%      stop.  All inputs are passed to vs_ManualData_OpeningFcn via varargin.
+%
+%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
+%      instance to run (singleton)".
