-==== Folder ====+=== Folder ===
  
 Each project records the individual folders where data files of the various types used by AMASS (//.raw//, //.cen//, //.cal//, //.seg//, //.c3d//) will be stored. Of course all data file types may also be stored in a single folder. When a user selects a file type by clicking on a radio button below the **Folder** box, the box’s entry will change to the folder that contains that file type for the current project, and the large **Input files** list box will display all files having that extension. For example, if the **cen** button is selected then the large list box will show all files that have the //.cen// extension that are contained in the folder displayed in the **Folder** box. Each project records the individual folders where data files of the various types used by AMASS (//.raw//, //.cen//, //.cal//, //.seg//, //.c3d//) will be stored.

 This button launches the C-Motion camera //**Capture2D**// program that can be used to collect .//cen// files from supported camera systems. The program is strictly not a part of AMASS but is designed to be run in parallel with the AMASS Shell and feed .//cen// files directly to AMASS functions.

-==== Convert ====+=== Convert ===
  
-The //**[[Other:AMASS:Documentation:Convert|Convert]]**// function provides a conversion capability from raw camera data files produced by some commercial systems to .//cen// files required by AMASS. This button becomes enabled if one or more camera raw data files are selected in the **Input files** list. The extension of the raw data files will depend upon the camera system that created the files, and the system type must first be set in the **Input** page of the Parameters dialog. For systems that produce individual camera files for each data capture only the lowest numbered file will be displayed in the input file list. The conversion process creates a single .//cen// file for each capture even if multiple camera files were produced by the originating system.+The //**[[Other:AMASS:Documentation:Convert_AMASS2|Convert]]**// function provides a conversion capability from raw camera data files produced by some commercial systems to .//cen// files required by AMASS.

If one or more .//cen// files are selected you can click on **ViewCen** to display the image data from each camera, over all frames. A **Parameter** button in the window also provides information on some internal camera parameters stored in the .//cen// file. If you check the **ViewCen** box in **Input** parameters, the //**ViewCen**// program will be automatically called after each file conversion. //**[[Other:AMASS:Documentation:Viewcen|ViewCen]]**// is a utility program for visually checking the quality of data in .//cen// files.

-==== Calibrate ====+=== Calibrate ===
  
-The AMASS //**[[Other:AMASS:Documentation:Calibrate|Calibrate]]**// program performs the camera system calibration from the selected input .//cen// file(s) using the **Calibrate** parameters in the current Project file. If successful it writes the resulting calibration data to a .//cal// file in the cal folder designated via the **Input files** group. This calibration file can then be used by the //**Track**// program to generate 3D marker trajectories. During a calibration data capture an [[Other:AMASS:Documentation:Calibrate#The_calibration_wand|AMASS wand]] must be moved throughout the volume where it is desired to perform 3D measurements. The requirements for wand motions during the calibration trial capture are rather specific, and must be carefully done in order to provide a successful and accurate calibration. An accurate calibration in turn leads to good, clean marker trajectories which makes the task of segment identification much easier.+The AMASS //**[[Other:AMASS:Documentation:Calibrate_AMASS2|Calibrate]]**// program performs the camera system calibration from the selected input .//cen// file(s) using the **Calibrate** parameters in the current Project file.

-The calibration software performs a series of complex computations in order to determine, among other things, each camera’s focal length, lens distortions, internal camera geometry, and location and orientation in the global coordinate system. Simultaneously the program also deduces the distribution of the markers on the wand, and the wand’s location in every frame. Examination of the required [[Other:AMASS:Documentation:Calibrate#Calibration_parameters|calibration parameters]] will show that user input to the program is very limited, greatly reducing the possibility of errors. However, it is important to read and pay close attention to the [[Other:AMASS:Documentation:System_calibration|System calibration]] section which provides detailed instructions on setting up cameras and collecting calibration data.+The calibration software performs a series of complex computations in order to determine, among other things, each camera’s focal length, lens distortions, internal camera geometry, and location and orientation in the global coordinate system.

 Every .//cal// file can be examined with the //**[[Other:AMASS:Documentation:Viewlin|ViewLin]]**// utility program. In addition to a view of the area of the image that was calibrated and can participate in 3D reconstruction for each camera, the display provides some overall information on the quality of the calibration. //**ViewLin**// also has an **Apply** button which designates the currently displayed .//cal// file as the calibration file to be used in subsequent //**Track**// operations. Every .//cal// file can be examined with the //**[[Other:AMASS:Documentation:Viewlin|ViewLin]]**// utility program.

-==== Track ====+=== Track ===
  
 The //**[[Other:AMASS:Documentation:Track|Track]]**// program acts on the selected .//cen// files to generate .//seg// files using the calibration file and **Track** parameters specified in the Project file. The tracking process is automatic and involves a complex computation that combines the centroids of each marker from different cameras, reconstructs the markers' locations in 3D space, and assigns the markers to 3D trajectories. These 3D trajectories extend over five or more consecutive frames and are called __segments__. The segments are arbitrarily numbered according to the order of their commencement, and typically vary in length because of interruptions due to marker image loss from camera views. The resulting .//seg// file is a binary file containing all possible segments that could be reconstructed from the .//cen// file. The //**[[Other:AMASS:Documentation:Track|Track]]**// program acts on the selected .//cen// files to generate .//seg// files using the calibration file and **Track** parameters specified in the Project file.

 //**[[Other:AMASS:Documentation:Viewseg|ViewSeg]]**// is a utility program that operates on the selected .//seg// files, and for each file provides a graphical overview of the number of segments generated by the tracking. It also shows the lengths of the segments with respect to the total number of frames processed. If **Connect gap** in the Track parameters is greater than zero then the //**Track**// program connects discontinuous segments which have a high probability of belonging to the same marker to form single segments. Hence the //**ViewSeg**// display may show gaps in some segments indicating that a marker could not be specifically tracked for one or more frames. //**[[Other:AMASS:Documentation:Viewseg|ViewSeg]]**// is a utility program that operates on the selected .//seg// files, and for each file provides a graphical overview of the number of segments generated by the tracking.
