Getting Started
                              
This package has been tested on Matlab 5.3.1 and 6.5.1 Service
Pack 1. The minimum requirement for this package is MATLAB
Version 5.3.1. To get started, you need to unzip the package 
into a new directory. After launching Matlab, you first add 
this new directory to the Matlab path.

Type 'plsgui' to start this Graphical User Interface.











- How to run PLS analysis in this GUI system.

Just like running PLS analysis using command line, running
PLS analysis under the GUI can be divided into 3 steps:
        1. Prepare datamat (data matrices)
        2. Run analysis on datamat
        3. Display results

Here, we use the 3 buttons 'Session Profile', 'Run PLS
Analysis', and 'Show PLS Result' to achieve the above 3
steps. The 'CLOSE' button will close this GUI system.









- Tools Menu

From the first window, you can select "Save GUI Positions"
under its "Tools" menu. If you did that, all windows positions
will be remembered in a file called "pls_profile.mat". If you
do not have permission to save this file, the program will
prompt you to save it somewhere else.

Instead of always using the default setting in the display panel
of the result window for PET, E.R.fMRI, or Blocked fMRI, the 
"Save Display Setting for PET/MRI" allows you keep the current 
setting you entered in the display panel of the result window.

For "Run PLS Analysis ..." and "Show PLS Result ...", program
will look for files on current directory. If they are not on
current directory, you can select "Change Current Working
Directory" to change it.



- Data that can be analyzed

This GUI system allows you to perform PLS analysis on PET
scans, ERP waveforms, Event Related fMRI scans, and Blocked
fMRI scans. (The default is for PET scan). You can choose
one of them to analyze by clicking the corresponding button.
Once you choose the data format, you will follow the above 3
steps to prepare datamats, run the analysis and view
results.


- Where are the help files?

All the help files end with '_hlp.txt', except this
'README.txt' help file. You can open them with any text
editor to view or print.

You can close the help file window by the window close
button defined in your operating system. You can also close
it by clicking the page number area.
