   *Once the centering points have been set up call your friend or acquaintance over to help you. Teach them how to bring up the grayscale and crosshairs on the camera screen, the options can sometimes change when changing from camera to camera, and have them direct you on where to angle the cameras to center them on the cross-hairs. Using the clamps pivots angle the cameras until they are centered on their corresponding marker. e.g. The top row of cameras on the marker on top of the tripod and bottom row on the ground plane marker. Please be careful when moving the cameras around as to not drop or damage them while doing this. The clamps pivots are also very sticky so may need some elbow grease to move around. Use the ladder to reach the top cameras and be careful while on top.
   *While centering the cameras check that there isn't any noise coming into the cameras from reflective surfaces. If the camera is picking up the lens of another camera, move it just enough to where it isn't in range anymore. It is ok if the camera isn't 100% centered in this case.

 . Calibrating the cameras through Arena
   *Once all of the cameras have been centered on their own respective markers remove the centering markers from within the volume and prepare the calibration wand and the calibration square.
   *click on the wizards menu and choose calibration, this will start the calibration wizard for the cameras. Click next on the pop-up window and follow the instructions to start the calibration phase.

 You have now finished calibrating the cameras and can now follow move onto the next section which will take you through how to setup a rigid body and then capture and export position-orientation data.

   *Once you have recorded the movement data right click it in the hierarchy tree on the left hand side of the gui within "take" and click trajectorize. This will create trajectories of the movement allowing you to see the change in x,y,z positions of each marker.
   *Now right the trajectory created under "trajectories" and choose export BVH. This will export the position and orientation data of the rigid body as a text file.

 ====Final Words====
 Congratulations you have now successfully created, tracked and exported position-orientation data of a rigid body you created! You are have completed this tutorial. If you have any other questions feel free to email me or check the [[http://wiki.optitrack.com/index.php?title=OptiTrack_Documentation_Wiki|opitrack wiki]] for more information not covered in this tutorial.

 Possible future tutorials that can be derived from this tutorial is the full body tracking of the DRC HUBO or quad-copters within a capture volume.
