function pushbutton1_Callback(hObject, eventdata, handles)

cd('D:\mim\dd - loop katz'); % current directory

fid = fopen(uigetfile('*.txt','Select the M-file')); %open and select file

data=textscan(fid,'%s %s %s %f %f'); % Read formatted data from text file

height=cell2mat(data(4)); %height at column 4

he=height;

tt=1:length(he);

axes(handles.axes2)

plot(tt,he)

function pushbutton2_Callback(hObject, eventdata, handles)

fs=str2num(get(handles.edit2,'String'));

y=fs; for z=1:fix(length(he)/fs); ns(z,:)=((y*(z))-y)+1:y*(z); % data by data. ex 1-9, 10-19...ect hxx=he(ns(:,:)); % import heigth on ns end hett=ns'; % time hex=hxx'; %
