These are both file formats that are widely used to store both raw biomechanics data (C3D), and well as processed gait data (C3D, DST and GCD). The MLS file viewer has a simple to use interface. Installation You can use the Windows Add/Remove Programs option in Control Panel to install the MLS file viewer from a floppy disk or CDROM. If you download a copy from User Guide C3D and DST file viewer Introduction • 1 our ftp site on the Internet (ftp.emgsrus.com), then just run the installation file. This will install the program on your system together with some example files that you can use to demonstrate and play with the program. During installation The MLS file viewer will prompt you to enter a license number - if you do not have a license then you can run in evaluation mode by entering 0000- 0000-0000-0000 as the serial number. If you have obtained a license to run the program from Motion Lab Systems then enter your license number together with your User Name and Organization details exactly as supplied on your license certificate.

The program (like all MLS programs) is a 32-bit Windows 95/NT application and will respond to all the normal commands to position and control the display. It can be represented on the screen in one of the three ways: full screen (maximized), as an application icon (minimized), or within a window (restored). The application remembers the state in which it was when it was last used and the size of the main window and the position of the Toolbar will be the same. The name of the current data file that is being analyzed will be displayed in the top left corner of the application (after the name of the Application). When more than one file is open the file name will be the name of the file window that is currently selected. You can view each file maximized (so that the entire view window fills the MLS file viewer application) or you can tile the file windows so that you can view the contents of the files simultaneously. At this point virtually all the commands that you will need are on the short-cut bar at the top of the program window. You can select items within any active data window simply by clicking on them to display their values or view the data.

The toolbar button has a drop down Shortcut – C TRL+O arrow, clicking on which will give you a list of recently opened files. This command can be used to open an existing data file. The application automatically determines the format of the file and reads the data from the file using the correct format and/or lexicon.

Each file is opened in its own window. A file can also be opened by dropping it into the application workspace or by double clicking on it in the Windows Explorer if the file type has been associated with this application. The following different data files are recognized by the application: DST Files The CAMARC file format defines a file format for the storage and exchange of data.
