respected sir i have code of content based medical image retrieval but this is not working,n when i want to run this code,it give some errors like >> CBIR CBIR Error using fileparts Too many output arguments. Error using fileparts Too many output ar

function varargout = CBIR(varargin)
%dbstop at 468 in CBIR
% CBIR M-file for CBIR.fig
%      CBIR, by itself, creates a new CBIR or raises the existing
%      singleton*.
%
%      H = CBIR returns the handle to a new CBIR or the handle to
%      the existing singleton*.
%
%      CBIR('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in CBIR.M with the given input arguments.
%
%      CBIR('Property','Value',...) creates a new CBIR or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before CBIR_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to CBIR_OpeningFcn via varargin.

Answer 1

[Walter Roberson]

You have two calls of the form

[newpath, name, ext, ver] = fileparts(filename);

one in listbox1_Callback and the other in selectionButton_Callback

Edit those to remove the ", ver", making

[newpath, name, ext] = fileparts(filename);

[SUMEET GAUR]

thank u so much sir..that error sort out but another error occurs like Error using cd

Cannot CD to C:\Project (Name is nonexistent or not a directory). Reference to non-existent field 'filename'. im waiting for ur answer

[Walter Roberson]

The code in selectButton_Callback has a call

cd('C:\Project');

If that directory does not exist then the line is going to error and the routine is going to exit without having done whatever it needs to do. In particular it is going to return before it has saved the value it has stored in handles.filename

The cd line should be changed to name the directory where the file database.txt is stored. It looks like it would need to be a writable directory as it creates several files.
