MEPHunter_Filter.m

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