[FieldTrip] GUi issue with ft_preprocessing

[Leila Ayoubian]

Why Data do not load in GUI, but it loads in a script using fieldtrip ft-preprocessing function?
 Look a the two code below. One which is a script work perfectly fine.The other one is inside a simple gui and Matlab crashes.....Can anyone enlighten me?!
Thanks in advance






function varargout = trial5(varargin)
% TRIAL5 MATLAB code for trial5.fig
%      TRIAL5, by itself, creates a new TRIAL5 or raises the existing
%      singleton*.
%
%      H = TRIAL5 returns the handle to a new TRIAL5 or the handle to
%      the existing singleton*.
%
%      TRIAL5('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TRIAL5.M with the given input arguments.
%
%      TRIAL5('Property','Value',...) creates a new TRIAL5 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before trial5_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to trial5_OpeningFcn via varargin.
