-==== Example 2 ====
-Open the text file that was just created. Select File -> Open. Select the viewer for .txt files. Select "aurora.txt".
-{{MergeAuroraFiles4.gif}}
-The file will be loaded into memory. The Aurora file contains position and rotation data for a rigid body. It will appear in Visual3D as LINKMODEL_BASED items containing the
-ORIGIN (3 components)
-QUATERNION (4 components).
-{{MergeAuroraFiles5.gif}}
-Visual3D typically works with motion capture markers, so to maximize your ability to work with this data, you can create a set of 3 targets per rigid body using the following command.
-**Create_Targets_For_LinkModelBased_Rotations**
-/SIGNAL_FOLDERS=Port_01+Port_02+Port_03+Port_04
-**;**
-Targets for each rigid body should appear in the data tree.
-It is possible to save this data to a C3D formatted file, but the LINK MODEL data (e.g. the ORIGINAL Translation and Quaternion will be lost, so it is recommended that you save this data to a cmo file.

-If you need a static trial for modeling the data, you can save the first frame of data to a c3d file.
