3. TRC Files

1. The TRC file is a coordinate data file for points, exporting the data coordinates of both named and unnamed points contained in the cap file into a single file.

2. In Edit Mode, after loading the capture data, click "File" and select "Export TRC File". The system will prompt that the export of the TRC file was successful; then click "Confirm" (13.3.1). The system saves the TRC file to the working path by default. The naming convention is cap file name + '-' + MarkerSet name + '.xrs'. The coordinate data of unnamed points is also exported by default, using the naming convention: cap file name + '-' + 'unnamed' + '.xrs'.

3. TRC files can be opened in Excel format, with data formats including "frame, time, timestamp, xyz coordinates" (13.3.2).

Export Reverse Calculation Marking Point Data

• In post-processing mode, load the CAP data with reverse calculation marking points. Click on File → Export TRC File. Open the TRC file using Excel, and it will display the XYZ data for each frame of every named point's reverse calculation marking points. If the named point of a rigid body is lost, the reverse points will automatically fill in and replace the original points, and the XYZ data of the original points will also be supplemented. The names of the reverse calculation marking points in the TRC file will be "RCalc_PointName" (13.3.3).
