MATLAB: How to input data using GUI inside a loop

guiuicontrol

I want to enable people to input several parameters, such as the number of headerlines, for each run inside the loop, by creating a simple GUI.
for i =1:200;
  file = ['data' num2str(i) '.txt'];
  if exist(file)==2;
  h = uicontrol('style','pushbutton', 'callback', '');
  N = get(h, 'String');
  [a b] = textread(file, '%f %f %f', 'headerlines', N); 
  end; 
end;
My question is, how do I program uicontrol, so that when people click the button, it will simply continue the program, rather than callback another m file?
Thank you.

I would use an INPUTDLG here.
prompt = {'Enter the number of header lines:'};
name = 'Header lines..';
for i =1:200;
   file = ['data' num2str(i) '.txt'];
   if exist(file)==2;
        N = inputdlg(prompt,name,1,{'1'});
        % Now to turn NLINES from a cell, use:
        N = N{1}
        [a b] = textread(file, '%f %f %f', 'headerlines', N); 
   end 
end
Although, as a user I would be bummed if I had to enter 200 header lines manually through a GUI each time through the loop. Perhaps it would be better to create a text file which has the number of header lines for each data file in it...
