how phow_caltech101.m categories change

I'm Jang, Korean, univ student.

I have a question about phow_caltech101.m, I use windows7

I'm studying Caltech101 using Matlab..

I wanted to classify and train the images of caltech-101 using phow_caltech.m file but there was a problem, I don't know how to change the categories...

these are what I did.

1. setup lv_setup

2. test version : vl_version verbose OK

3. vl_demo OK

4. make m_file phow_caltech101.m (copy)

5. I downloaded caltech101 images at here http://www.vision.caltech.edu/Image_Datasets/Caltech101/ by myself and copied to data/caltech-101

6. >>phow_caltech101 (in command widnow) - I saw fixed example categories (BACKGROUND_Goole, Faces, Faces_easy, Leopards, Motobikes)

I've tried to change the example categories(BACKGROUND_Goole, Faces, Faces_easy, Leopards, Motobikes)

I want to use categories ( accordion, airplanes, anchor, ant in caltech-101) - this is my point

I changed some codes of phow_caltech101.m but it didn't work...nothing has changed...

plz give me some advice ... help me

where should I change ?

I look forward to replying your mail thank you~!
