How to select multiple input file one at a time.

I have written a code in matlab with dialog box to open an input data file using diretorio = uigetdir; filename = uigetfile('*.txt','Select the INPUT DATA FILE');,

I do some process and produce the output using

prompt=('OUTPUT FILE NAME with .xls ext: '); title3='Output file name';

I have to run the same program for different input data files. Every time i run the program I feed the input file and get the ouput. Actually after the input data file is processed and the output file is created, the program should go to diretorio = uigetdir; for selecting another input file for processing / selection. Since there is no goto option in matlab, how to solve this. Can anyone help. Thanks in advance. Mohan.

Several options depending on what you want/need...

a) if you're processing all the *.txt files in a subdirectory, there's no reason to have to select each manually -- use something like

d=dir('*.txt');
for ix=1:length(d)
  fn=d(i).name
  ... do processing here, save results w/ dynamic output file name...
  ...
end

b) if you aren't doing all but know which ones, use uigetfile() but use the multipleselection optional input option --

fn=uigetfile('*.txt','Select the INPUT DATA FILE(s)','MultiSelect','on');

Then use a loop like above except the filenames are in the cell string array instead of a structure

Or,

c) if you really do need to select manually each time, just wrap your code in a while() loop and continue as long as there is a valid selection each time through...

flg=true;   % set the logic variable to start the loop
while flg
  fn=uigetfile('*.txt','Select the INPUT DATA FILE(s)','MultiSelect','on');
  if isequal(filename,0), flg=0; break; end   %  no file selected; quit
  % otherwise process as above here
  ...
end

I have few readings (each reading is a batch of 6 sequences ) .

Further each sequence has 4 parameters (not so important at this point )

i have to seperate the two different sequences (in group of 4 and 2). Hoe should the filter be like for file selction?
