 ===New Project===
 At the start of your experiment, or whenever you have made significant changes to the setup/configuration, you should create a new QTM project. You can do this when launching QTM -> New Project, or File -> New Project if you already have a project open.
 Give your project a distinct name (preferably includes your personal and/or research-project name) and select the project folder path. The folder is best located inside your own user folder on the D:/ drive. Create one if you haven't already.
-We often recommend basing the new project on an existing project, which is an option in the New Project window. This will copy all settings, 6DOF bodies, AIM models and scripts from a previous project; saving you some time setting things up.
+===Rigid Body Tracking===
-Choose 'Base the project on: "Settings Imported from another project"' and select the Settings.qtmproj file from the base project.
+Rigid bodies can be saved and loaded via Project Options -> Processing -> 6DOF Tracking. This is handy when using common objects between multiple projects.
-<!--===Rigid Body Tracking=== TODO-->
+===Automatic Identification of Markers (AIM)===
 ===LSL===
 Data from QTM can be streamed in real-time, as well as in playback-mode, via LSL using the [https://github.com/qualisys/qualisys_lsl_app Qualisys LSL App]. Only labeled markers (3D) and rigid bodies (6DOF) can be streamed over LSL.

 If you wish to capture motion with a Qualisys system, please contact the TSG. They will assist you in determining which system is best suited for your needs and, when available, will set it up for you in one of our research labs.
 A training session with [[Erik van den Berge]] is required before you can use the system.

+==Cameras==
 A Qualisys system is an optical motion capture system, meaning it uses cameras to record motion of your subject. This is traditionally done with markers, which emit or reflect infrared light that can be captured by the cameras. By placing multiple cameras in different locations, the system can triangulate the position of a marker.

 Choice of marker size depends on the subject and the distance between the subject and the cameras. The smaller the subject (e.g. baby's fingers), the smaller the marker needs to be. But the smaller the marker, the higher the resolution or the closer the camera should be to capture it.
-The benefit of using passive markers is that they are (relatively) cheap, and they need no cables for power or anything. The downside is that passive markers are not inherently identifiable, meaning they need to be manually labeled afterwards and cannot be streamed in real-time unless they are part of a rigid body.

A rigid body is an object with 3 or more markers
-==Active Markers==
+All optical markers (both active and passive) have the disadvantage of being easily obscured (something blocking the view from the cameras to the marker, making it impossible to track). Therefore, marker placement has to be considered carefully, and often it is wise to place additional markers for redundancy. Standard marker placement templates exist for full/partial body tracking.
 Active markers are markers that emit infrared light themselves. They require an active power source (meaning they're attached to cables), but they can potentially work over longer distances, and most of all they can be individually identified.
