================================================================

Download the virtual disk file from:
http://gv2.usc.edu/ugesce/SEATREE64-2013.vdi.tgz
or
http://gv2.usc.edu/ugesce/SEATREE64-2013.zip

and then unzip/untar the file as necessary; that is, gunzip or
unzip, and then, if needed 

tar xvf SEATREE64-2013.vdi.tar

You should end up with the file:

SEATREE64-2013.vdi


--- Installing the virtual Linux machine within VirtualBox ---

- start VirtualBox

- select "new" from menu

- choose Linux-Fedora (64bit) as operating system, and use something
  like "SEATREE-2013" as a name

- use default memory suggestions 

- select the radio button for "Use an existing virtual hard drive";
  click the folder icon with the green symbol to the right of the
  drop-down menu;
  navigate to the .vdi file you downloaded, and select that file;
  then click "Create" 

- if this step is successful, your new Linux virtual machine should
  show within VirtualBox as "SEATREE-2013".



--- Using the Linux machine (LOGIN) ---

- Start the SEATREE-2013 virtual machine

- If the machine is running, you should see a Fedora/Linux login
  screen with one user, the "Seatree User". Click on the user icon,
  and login
 
User: seatreeuser 
Password: seatree 

- type "seatree" in the command window (or you can open it with the
  icon on the desktop)

* For this tutorial:

select "Larry - 2D Tomography 1.0" from the drop-down menu;
we will also use the module "Syn2D - 2D Cartesian Tomography 1.1"


--- Troubleshooting if your image will not boot ---

- Make sure the visualization setting for you CPU is enable in your BIOS.
