Setting up the desktop environment
Before we start Corelyzer, we must first make sure our display settings are correct. On both the Mac and Windows, the default monitor should be placed as the upper left most monitor.
Windows Users
To setup the monitors on windows, you must first go to your display settings. You can do this by going to your Start menu, selecting Control Panel and finally double-clicking on Display Settings.

Once opened, please go to the Settings tab. Here you will see boxes with numbers, and below those options that can be adjusted. The boxes with numbers represent your monitors that you have connected to your machine. If you have a monitor that is not displaying your desktop then it will show up as a slightly greyed-out box, which is a visual description that says this monitor is disabled. If the box indicates the monitor is disabled and you click on the box, you will be able to modify the options for that monitor. To enabled the monitor, make sure that the check box next to Extend my desktop... is checked. Do this for all the monitors you would like to use, presumably all of them. Once you have done that, click on the Apply button. If you did this correctly, you will have your desktop visible on all the monitors. Note: Some monitors need to be turned off and on again to realize that they are enabled by Windows.

Now that the desktops are visible on your monitors, you will need to set the display resolution for all of the monitors. Corelyzer requires that you set your display settings so that all the monitors will have the same resolution. Example resolutions are 1280x1024 and 1600x1200. There is a slider on your display settings dialog to modify the resolution. Once set for all monitors, click on the Apply button again. If you are prompted to restart your machine in order for the changes to take affect, then do so. Otherwise, the resolution of your monitors will change and you will be prompted to keep the settings or change them back. Note: If your monitors do not support a particular resolution they will likely display that or they will stay black. If you do not like your settings, wait for some time and Windows will revert back.
TODO: Show example of monitors with same resolution
After you have enabled your monitors and configured their display settings, you should make sure that the layout of the monitors matches the layout of the boxes in your display settings. First we need to identify which box represents which monitor, and we can do this by seeing what number has been assigned to each monitor by Windows. To do this click on the Identify button. When you do this, your monitors will display a number indicating which box refers to which monitor. If your monitors are ordered differently than the boxes that are shown on your display settings, then you will need to re-arrange your monitors. This is easily done by clicking and dragging the boxes in your settings window. Again, you should make sure that the upper left most box matches with your upper left most monitor and that montior is enabled as your Primary Monitor.

Mac Users
To setup your monitors on your Mac you will need to get to the display settings. To do this open the System Preferences application in your Applications directory. Then choose Displays and you will see a dialog window on each monitor that is connected to your machine.
Make sure the display resolution on each monitor is the same. After fixing the resolution, go to your main window and select the Arrangement tab. You will then see a layout of boxes that indicate how your monitors are layed out. Unfortunately there is no way to identify which monitor is represented by which box, as you can on Windows. You will need to arrange the boxes to match your monitor arrangement.
To re-iterate, you will have to make sure the upper left most monitor in your arrangment will be the main monitor. On the Mac, the main monitor is visible in the Arrangement tab as the box that contains a white rectangle along the top of the box. To designate a different monitor to be the main monitor, simply drag the white rectangle to the box that should be the main monitor. This white rectangle is actually the menu bar you see on top of your monitor. Once the rectangle has been moved, the menu bar will also move.
If you are making a presentation then you may want to mirror your display, but normally you don't want to mirror your display so that you will have more screen real-estate to view your core images and data.
Starting Corelyzer
To start Corelyzer double click on the Corelyzer icon. If the Java Runtime Environment is correct, as per directed in Pre-installation Requirements, and you start up Corelyzer for the first time, a preferences configuration window will show up. The window is the Corelyzer Preferences window. Using this preferences window you can specify your scratch disk location, display settings, and some user interface features.
Directories Panel
Corelyzer will use part of your hard disk to store pre-processed different levels of imagery blocks. Also, for some images that are not available in user’s machine, but their URLs are provided, Corelyzer can download them to the download directory specified here. It is recommended to select a bigger and fast hard disk.
Display Configuration Panel
Here you can set the display configuration that Corelyzer will use. More often than not you will have it match the display configuration you setup with your operating system (See above sections). The Display Configuration window will store your settings. Once you have set this up the first time, Corelyzer will load the saved configurations every time after without popping up the preferences window.
Once ‘OK’ button is clicked a window (or multiple windows) will be created, according to your configuration, for the visualization display, as shown below.
Here we can see that the visualization window is pretty empty, so let's start adding data and imagery.
