Subject prefixes are used within the C3D file to distinguish between subjects. Visual3D include subject prefixes as part of its Multisubject support. Subject prefixes should not be confused with Subject Tags, which allow users to associate a generic label (a tag) with a subject in a C3D file
The C3D file contains a parameter to specify the subject prefix. This should be specified by your motion capture system and can be different from C3D file to C3D file
For multisubject data, specifying a subject prefix in the Model Builder tab allows users to select which subject to create segments for.
