-This pipeline command allows you to remove the specified prefix(es) from [[visual3d:documentation:c3d_signal_types:target_data_type|TARGET]] (marker) names within the active files.+Some motion capture manufacturers' software provides an option to add a prefix to all of the marker labels. This has the potential to cause a big problem when reading these files in Visual3D, since an assumption is made that markers are named consistently between files, especially between the standing trial and the movement trials. This pipeline command allows users to remove the specified prefix(es) from [[visual3d:documentation:c3d_signal_types:target_data_type|TARGET]] (marker) names within the active files.

-Some motion capture manufacturers' software provides an option to add a prefix to all of the marker labels. This has the potential to cause a big problem when reading these files in Visual3D, since an assumption is made that markers are named consistently between files, especially between the standing trial and the movement trials.+===== Command Parameters =====
  
-This command can be used to remove the marker prefix from [[visual3d:documentation:c3d_signal_types:target_data_type|TARGET]]s.+^ Parameter ^ Description ^ 
 +| **Prefix** | If specified, only this prefix will be removed from the signal names. If left blank, Visual3D looks for the [[visual3d:documentation:c3d_signal_types:c3d_format#c3d_parameter_format|C3D Parameter Group]] called "SUBJECTS" and the parameter "LABEL_PREFIXES". This could contain several entries, and Visual3D searches the [[visual3d:documentation:c3d_signal_types:target_data_type|TARGET]]s for signal names containing these prefixes and the prefix is removed from the name. | 
 +| **Include Cal File** | If TRUE, the model files will be modified as well. | 
 +| **Overwrite C3D File** | If TRUE, the modified C3D file will be saved over the current file on disk. **Use with caution**. It is recommended that the parameter be set to FALSE in most cases so that the new names can be verified. The files can then be exported in an independent command.|
  
-=== /Prefix Parameter === +===== Example =====
- +
-If the PREFIX parameter is specified, only this prefix will be removed from the signal names. +
- +
-If the PREFIX parameter is left blank, Visual3D looks for the [[visual3d:documentation:c3d_signal_types:c3d_format#c3d_parameter_format|C3D Parameter Group]] called "SUBJECTS" and the parameter "LABEL_PREFIXES". This could contain several entries, and Visual3D searches the [[visual3d:documentation:c3d_signal_types:target_data_type|TARGET]]s for signals containing these names and the prefix is removed from the name. +
- +
-We have seen instances where the manufacturer stores these values incorrectly. In this case, the user should manually specify the prefix and the C3D Parameters are ignored. +
- +
-=== /Include_Cal_File === +
- +
-If TRUE, the model files will be modified as well. +
- +
-=== /Overwrite_C3D_File === +
- +
-If TRUE, the modified c3d file will be exported. +
- +
-Use this parameter with caution. It is recommended that the parameter be set to FALSE in most cases so that the new names can be verified. The files can then be exported in an independent command. +
