Download the appropriate demo version

Download the demo software that is appropriate for your version of Matlab
To find out what version of Matlab you have, type "version" in the Matlab command window. Contact ImagEval if your version is not listed below

• 7.7.0.471 (R2008b) and later versions (R2009a, R2009b)
• 7.5 (R2007b)
• 7.4.0.287 (R2007a)
• 7.0.1.24704 (R14)

Contact ImagEval to obtain the password to unzip the downloaded software and a 30-day usage key.

Once you have downloaded and unzipped ISET-3.0, there remain a few steps you should follow to install the program.
First, you should set up your MATLAB® path.
Second, you should enter your Key

Path Management

The main purpose of these instructions is to make sure that your MATLAB® path is set up correctly for your version of MATLAB®. 

We refer to the location of the ISET-3.0 directory on your system as ISETDIR.  For example, this might be ‘C:\MATLAB7\work\ISET-3.0’.

1.  [Required]. ISET-3.0 is distributed containing MEX-files that are compiled for different versions of MATLAB®.  We recommend that you keep only the directory with MEX-files that are appropriate for your MATLAB® version.  To do this 

• Using Windows Explorer view the ISETDIR
• Remove the subdirectory DLL65 (if you use MATLAB® 7.0) or remove DLL70 (if you use MATLAB® 6.5) 

You only need to do this once.

2.  [Required]. Next, you must set the MATLAB® path to include the directories containing ISET-3.0 functions.  The function (isetPath.m), located in ISETDIR, automates the process of setting the MATLAB® path. 

After you start MATLAB®, you should type

cd ISETDIR
isetPath(pwd) 

This will include the ISET-3.0 functions on your path for this session.

3.  [Optional] Notice that to run isetPath(), you had to change to the ISETDIR.  That is because isetPath() may not always be on your MATLAB® path.  We have a suggestion about how you should manage your MATLAB® paths.  We have found this method helpful because in our work we use many different MATLAB® packages.

• Create a personal directory called ‘paths’.  If you are the only user of MATLAB® on a PC, you might create the directory ‘C:\MATLAB7\work\paths’.    We will continue the example with this example location for your directory.
• Run MATLAB®
• From the MATLAB® pull down menus, choose File | Set Path … .  This will open a small window.
• Click on the ‘Default’ button at the bottom of the window.  This will set MATLAB®’s path to its default state.
• Click on the ‘Add Folder’ button at the left.
• Choose the folder ‘C:\MATLAB7\work\paths’ and add it to your path
• Save your path
• Click on Close to exit the Set Path window.
• Copy the ISET-3.0 function, isetPath.m, into the folder ‘C:\MATLAB7\work\paths’.

Now, whenever MATLAB® starts, it will have the directory ‘C:\MATLAB7\work\paths’ on its path.  Hence, you can run isetPath(ISETDIR) without changing to the ISET-3.0 directory. The ISET-3.0 routines will be added to your MATLAB® path for that session. 

We suggest that you create functions like isetPath() to control the MATLAB® path when you are running other packages.

4.  Finally, if you would like to include the ISET-3.0 directories on your path every time you open up MATLAB®, you can follow the following simple procedure.

Create a script in a file called ‘startup.m’ and place it inside of ‘C:\MATLAB7\work\paths’.  Each time you start MATLAB®, this script will be invoked.  If the script contains the lines

isetPath(ISETDIR);

the ISET-3.0 functions will be added to your path each time you start MATLAB®.  If you would like to be given the option of running ISET-3.0 or another package, the startup.m file might contain simple code such as

isetDir = 'C:\MATLAB7\work\ISET-3.0;
pdcDir = 'c:\MATLAB7\work\PDC; 
R = input('Enter: 1 (ISET) or 2 (PDC) or 3(NONE):'); 
switch R  
case 1
isetPath(isetDir);
case 2
pdcPath(pdcDir);
otherwise
disp('No ISET, PDC or VISTA set.')
end 
clear R

Key Installation

To use ISET, open MATLAB®

cd (change directory) to the ISET-3.0 directory
type "d=pwd;"
then type "isetPath(d)"
then type "ISET"

The main ISET window will open.  Before you can run ISET,

• Select the "Store Key" option from the Initialize menu in the main ISET window.
• Type (Paste) the key into the window that is opened and select "OK"

You only need to follow the procedure described above the first time you launch ISET.
Thereafter, you only need to set your isetPath and type ISET.

After 30 days, the key will expire and you will no longer be able to use ISET:vCamera.

Microsoft Visual C Libraries (dll)

ISET requires certain system libraries relating to Visual C be in the WINDOWS\SYSTEM2 folder. These dlls are present on most systems, but we have had reports of cases in which the libraries are absent. If ISET does not run properly, please check to see that these two libraries (msvcp70.dll and msvcr70.dll) are in the WINDOWS\SYSTEM32 folder.

If these file are NOT in your system folder, then copy them from the ISET distribution to the WINDOWS\SYSTEM32 folder. Specifically, copy
